description: Vitamin K-dependent carboxylase, purified from bovine liver, has properties similar to those reported for the carboxylase activity present in crude, solubilized microsomes. The purified carboxylase was found to possess the vitamin K epoxidase activity, believed to be essential for vitamin K-dependent carboxylation, but did not contain vitamin K epoxide reductase activity. Kinetic studies of the carboxylase done under defined conditions were complicated by the non-Michaelis-Menten kinetic behavior observed for reactions with two of the enzymes substrates, FLEEL and vitamin K1 hydroquinone. Initial rate experiments with the substrate FLEEL demonstrated behavior consistent with substrate inhibition and gave half-maximal activity at 1 mM FLEEL. Experiments with the substrate vitamin K1 hydroquinone also displayed non-Michaelis-Menten kinetics, as maximal activity was reached prematurely in relation to behavior at lower concentrations. Half-maximal activity was observed at 35 microM vitamin K1 hydroquinone. Initial rate experiments with varying NaH14CO3 concentration displayed Michaelis-Menten kinetics and gave a Km(app) of 0.29 mM. At cosubstrate concentrations chosen to obtain near-maximal activity, initial rate studies with varying NaH14CO3 concentration indicated a kcat near 1.0 s-1. Removal of the fourth substrate, oxygen, resulted in the loss of more than 99% of carboxylase activity. The sulfhydryl reagent N-ethylmaleimide inhibited carboxylase irreversibly, as did the anticoagulant warfarin.

description: Power-law-distributed species counts or clone counts arise in many biological settings such as multispecies cell populations, population genetics, and ecology. This empirical observation that the number of species $c_{k}$ represented by $k$ individuals scales as negative powers of $k$ is also supported by a series of theoretical birth-death-immigration (BDI) models that consistently predict many low-population species, a few intermediate-population species, and very high-population species. However, we show how a simple global population-dependent regulation in a neutral BDI model destroys the power law distributions. Simulation of the regulated BDI model shows a high probability of observing a high-population species that dominates the total population. Further analysis reveals that the origin of this breakdown is associated with the failure of a mean-field approximation for the expected species abundance distribution. We find an accurate estimate for the expected distribution $\langle c_k \rangle$ by mapping the problem to a lower-dimensional Moran process, allowing us to also straightforwardly calculate the covariances $\langle c_k c_\ell \rangle$. Finally, we exploit the concepts associated with energy landscapes to explain the failure of the mean-field assumption by identifying a phase transition in the quasi-steady-state species counts triggered by a decreasing immigration rate.

description: Heavy-quark effective theory (HQET) is applied to lattice QCD with Wilson fermions at fixed lattice spacing a. This description is possible because heavy-quark symmetries are respected. It is desirable because the ultraviolet cutoff $1/a$ in current numerical work and the heavy-quark mass $m_Q$ are comparable. Effects of both short distances, a and $1/m_Q$, are captured fully into coefficient functions, which multiply the operators of the usual HQET. Standard tools of HQET are used to develop heavy-quark expansions of lattice observables and, thus, to propagate heavy-quark discretization errors. Three explicit examples are given: namely, the mass, decay constant, and semileptonic form factors of heavy-light mesons.

description: We investigate the exclusive electroproduction of pi^+ mesons from nucleons. To leading twist, leading order alpha_s accuracy the corresponding production amplitude can be decomposed into pseudovector and pseudoscalar parts. Both can be expressed in terms of quark double distribution functions of the nucleon. While the pseudovector contribution is connected to ordinary polarized quark distributions, the pseudoscalar part can be related to one pion t-channel exchange. We observe that the pseudovector part of the production amplitude is important at x < 0.1. On the other hand, for 0.1 < x < 0.4 contributions from one pion exchange dominate.

description: Given a word, we are interested in the structure of its contiguous subwords split into $k$ blocks of equal length, especially in the homogeneous and anti-homogeneous cases. We introduce the notion of $(μ_1,\dots,μ_k)$-block-patterns, words of the form $w = w_1\cdots w_k$ where, when $\{w_1,\dots,w_k\}$ is partitioned via equality, there are $μ_s$ sets of size $s$ for each $s \in \{1,\dots,k\}$. This is a generalization of the well-studied $k$-powers and the $k$-anti-powers recently introduced by Fici, Restivo, Silva, and Zamboni, as well as a refinement of the $(k,λ)$-anti-powers introduced by Defant. We generalize the anti-Ramsey-type results of Fici et al. to $(μ_1,\dots,μ_k)$-block-patterns and improve their bounds on $N_α(k,k)$, the minimum length such that every word of length $N_α(k,k)$ on an alphabet of size $α$ contains a $k$-power or $k$-anti-power. We also generalize their results on infinite words avoiding $k$-anti-powers to the case of $(k,λ)$-anti-powers. We provide a few results on the relation between $α$ and $N_α(k,k)$ and find the expected number of $(μ_1,\dots,μ_k)$-block-patterns in a word of length $n$.

description: Total internal reflection fluorescence microscopy has been used to compare the membrane binding characteristics of fluorescein-labeled bovine prothrombin and fluorescein-labeled bovine prothrombin fragment 1. The Ca(2+)-dependent association of these proteins with quartz-supported planar membranes composed of mixtures of phosphatidylserine (2-10 mol%) and phosphatidylcholine was examined. Equilibrium binding measurements showed that the apparent equilibrium dissociation constants increased with decreasing molar fractions of phosphatidylserine and that the dissociation constants were somewhat lower for intact prothrombin. Kinetic measurements, using fluorescence photobleaching recovery, showed that the measured dissociation rates were approximately equivalent for prothrombin and fragment 1 and did not change with the protein solution concentration or the molar fraction of phosphatidylserine. The kinetic data also implied that the surface binding mechanism for both proteins is more complex than a simple reversible reaction between monovalent proteins and monovalent surface sites. Measured equilibrium and kinetic constants are reported and compared for prothrombin and fragment 1 on planar membranes.

Four species of maltose-binding protein containing aminoacyl substitutions identified as decreasing the rate of folding of the protein in vivo were purified, and their denaturant-induced folding transitions were analyzed by monitorin8 the intrinsic fluorescence of tryptophan. In all four cases the rate of folding in vitro was slower than that of the wild-type maltose-binding protein; thus the same step determines the rate of folding in vivo and in vitro.The folding of maltose-binding protein, a periplasmic protein in Escherichia coli, was shown to proceed through the same rate-limiting step whether folding occurred in the cell under physiological conditions or in vitro in the absence of other proteins.

description: Answers to the metal production of the Universe can be found in galaxy clusters, notably within their Intra-Cluster Medium (ICM). The X-ray Integral Field Unit (X-IFU) on board the next-generation European X-ray observatory Athena (2030s) will provide the necessary leap forward in spatially-resolved spectroscopy required to disentangle the intricate mechanisms responsible for this chemical enrichment. In this paper, we investigate the future capabilities of the X-IFU in probing the hot gas within galaxy clusters. From a test sample of four clusters extracted from cosmological hydrodynamical simulations, we present comprehensive synthetic observations of these clusters at different redshifts (up to z = 2) and within the scaled radius R500 performed using the instrument simulator SIXTE. Through 100 ks exposures, we demonstrate that the X-IFU will provide spatially-resolved mapping of the ICM physical properties with little to no biases (<5%) and well within statistical uncertainties. The detailed study of abundance profiles and abundance ratios within R500 also highlights the power of the X-IFU in providing constraints on the various enrichment models. From synthetic observations out to z = 2, we also quantify its ability to track the chemical elements across cosmic time with excellent accuracy, and thereby to investigate the evolution of metal production mechanisms as well as the link to the stellar initial mass-function. Our study demonstrates the unprecedented capabilities of the X-IFU in unveiling the properties of the ICM but also stresses the data analysis challenges faced by future high-resolution X-ray missions such as Athena.

Functional complementarity between the HMG1-like yeast mitochondrial histone HM and the bacterial histone-like protein HU
Creators: name: Chae, C B
name: Megraw, T L
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: The mitochondrial histone HM is the major DNA-binding protein in mitochondria and is necessary for maintenance of the mitochondrial genome in the yeast Saccharomyces cerevisiae during growth on fermentable sugars. HM and the Escherichia coli histone-like protein HU have similar activities in vitro, including DNA supercoiling, but share no sequence similarity. We show that HU can functionally complement the respiration deficiency associated with yeast strains lacking HM. Conversely, phenotypes of E. coli cells lacking HU protein, including nucleoid loss and a filamentous cell morphology, were alleviated by expression of HM in these cells. The HU protein of bacteria and the HM protein of mitochondria are therefore functionally complementary in vivo. Functional similarities among HM, HU, and the nuclear HMG1 proteins are implicated and discussed.

description: We analyze the influence of spatial orientation on the optical response of hydrogenated silicon quantum wires. The results are relevant for the interpretation of the optical properties of light emitting porous silicon. We study (111)-oriented wires and compare the present results with those previously obtained within the same theoretical framework for (001)-oriented wires [F. Buda {\it et al.}, {\it Phys. Rev. Lett.} {\bf 69}, 1272, (1992)]. In analogy with the (001)-oriented wires and at variance with crystalline bulk silicon, we find that the (111)-oriented wires exhibit a direct gap at ${\bf k}=0$ whose value is largely enhanced with respect to that found in bulk silicon because of quantum confinement effects. The imaginary part of the dielectric function, for the external field polarized in the direction of the axis of the wires, shows features that, while being qualitatively similar to those observed for the (001) wires, are not present in the bulk. The main conclusion which emerges from the present study is that, if wires a few nanometers large are present in the porous material, they are optically active independently of their specific orientation.

description: We studied the consequences of cystic fibrosis transmembrane conductance regulator (CFTR) expression in NIH-3T3 fibroblasts as a model for the effects of virally transduced CFTR expression in non-epithelial cells. Fibroblasts were infected with a retrovirus vector that contained the human CFTR and neor cDNAs. We selected and expanded G418-resistant clones that encompassed a range of CFTR expression. CFTR-mediated Cl-conductance function was measured as whole cell current, and CFTR protein was quantitated by immunoblot analysis. Overall, there was a good relationship between CFTR protein levels and CFTR-mediated Cl- conductance. Some clones had consistently high basal levels of CFTR-mediated Cl- conductance. This variation in function was partially explained by CFTR protein levels and was not due to clonal variation in cAMP metabolism. High levels of CFTR expression were associated with depolarization of fibroblast membrane potential. The CFTR-expressing clones with the largest basally active CFTR Cl- conductances and the most depolarized membrane potentials also exhibited slower growth rates. These results suggest that potential side effects of gene replacement therapy for cystic fibrosis include functional consequences of CFTR expression in non-epithelial cells.

description: Starting from relativistic quantum field theories, describing interacting nucleons and pions coupled to the dynamical electromagnetic field, the pion degrees of freedom are eliminated by means of functional integration. Apart from taking into account some operators perturbatively in $e$, e.g. the vacuum polarization, this procedure is exact, giving effective theories for nucleons and photons. The subsequent nonrelativistic reduction yields the corresponding nonrelativistic quantum field theory. The latter is unique, irrespective of the precize form of the original nucleon-pion interaction. Nucleonic potentials and electromagnetic interactions are mutually consistent. Local gauge invariance is satisfied at any stage of the formal developments.

description: Human factor XSanto Domingo is a form of coagulation factor X in which a mutation within the signal peptide region of the precursor protein has been correlated genetically with a severe deficiency of factor X in the affected individual. A point mutation results in substitution of Arg for Gly at the critical -3 position of the factor X signal peptide. To determine the biochemical effect of this mutation on the biosynthesis of factor X, the wild-type and mutant factor X cDNAs were subcloned into a vector for transcription and translation in vitro. Translation products of mRNAs encoding portions of both mutant and wild-type proteins were used in a systematic biochemical approach to evaluate directly the effect of the mutation on targeting, transport, and proteolytic processing in vitro. The results show that targeting and transport of factor XSanto Domingo to the endoplasmic reticulum are functionally dissociated from the removal of the signal peptide by signal peptidase. Factor XSanto Domingo is translocated into the endoplasmic reticulum but not processed by signal peptidase. Transient expression of the wild-type and mutant factor X in human embryonic kidney 293 cells revealed apparently normal secretion of the glycosylated two-chain form of factor X but no secretion of factor XSanto Domingo. Thus, the inability of signal peptidase to cleave factor XSanto Domingo is directly responsible for the absence of circulating factor X and leads to the bleeding diathesis in the affected individual.

description: We study the effects of dynamical quarks on the static quark potential at distances shorter than those where string breaking is expected. Quenched calculations and calculations with three flavors of dynamical quarks are done on sets of lattices with the lattice spacings matched within about one percent. The effect of the sea quarks on the shape of the potential is clearly visible. We investigate the consequences of these effects in a very crude model, namely solving Schroedinger's equation in the resulting potential.

These genes are generally co-expressed in various cell types and coordinately induced by cytokines such as interferon-γ (IFN-γ). Human Ii gene shares a regulatory mechanism with MHC class II genes via the X and Y cis-acting elements. Ii X and Y are required for constitutive expression in B lymphoid cell lines and for induction by IFN-γ in a glioblastoma cell line. The Servenius element (S) contributes 5-fold transcriptional activity to class II gene HLA-DRA and an S homologue has been implied in Ii gene regulation.Major histocompatibility complex (MHC) class II-associated invariant chain (Ii) gene and the MHC class II molecules are physically and functionally associated within clans II-expressing cell types.

description: The drag reduction induced by superhydrophobic surfaces is investigated in turbulent pipe flow. Wetted superhydrophobic surfaces are shown to trap gas bubbles in their asperities. This stops the liquid from coming in direct contact with the wall in that location, allowing the flow to slip over the air bubbles. We consider a well defined texture with streamwise grooves at the walls in which the gas is expected to be entrapped. This configuration is modelled with alternating no-slip and shear-free boundary conditions at the wall. With respect to classical turbulent pipe flow, a substantial drag reduction is observed which strongly depends on the grooves' dimension and on the solid fraction, i.e. the ratio between the solid wall surface and the total surface of the pipe's circumference. The drag reduction is due to the mean slip velocity at the wall which increases the flow rate at a fixed pressure drop. The enforced boundary conditions also produce peculiar turbulent structures which on the contrary decrease the flow rate. The two concurrent effects provide an overall flow rate increase as demonstrated by means of the mean axial momentum balance. This equation provides the balance between the mean pressure gradient, the Reynolds stress, the mean flow rate and the mean slip velocity contributions.

description: Serine phosphorylation of insulin-like growth factor binding protein-1 (IGFBP-1) has been shown to alter its affinity for the insulin-like growth factors (IGF-I and IGF-II) and to modify its capacity to modulate cellular responses to the IGFs. Because of this, we determined the sites of serine phosphorylation. Purification of 32P-labeled IGFBP-1 was followed by digestion with trypsin and endoproteinase Glu-C and radiosequencing of labeled peptides. Three serines were found to be phosphorylated, with Ser101, Ser119, and Ser169 containing 70%, 5%, and 25% of the incorporated 32P, respectively. A mutated IGFBP-1, substituting alanine for serine at positions 98 and 101, was expressed in CHO cells. On nondenaturing gels, the wild type protein migrated as five isoforms (one non-phosphorylated and four phosphorylated). However, in the mutated protein, the most rapidly migrating band (a phosphorylated form) was not present. The cells containing the mutated cDNA incorporated 60% less 32P into immunoprecipitable IGFBP-1. The mutated protein had a 3-fold reduction in affinity for IGF-I compared to the wild type protein. We conclude that Ser101 represents the major site of phosphorylation containing 63% of the total 32P incorporated and that phosphorylation of Ser101 is important for maintenance of high affinity binding for this growth factor.

Aharonov-Bohm oscillations and resonant tunneling in strongly correlated quantum dots

description: We investigate Aharonov-Bohm oscillations of the current through a strongly correlated quantum dot embedded in an arbitrary scattering geometry. Resonant-tunneling processes lead to a flux-dependent renormalization of the dot level. As a consequence we obtain a fine structure of the current oscillations which is controlled by quantum fluctuations. Strong Coulomb repulsion leads to a continuous bias voltage dependent phase shift and, in the nonlinear response regime, destroys the symmetry of the differential conductance under a sign change of the external flux.

description: Two small interstitial dermatan sulfate-containing proteoglycans, biglycan and decorin, are present in extracellular matrices of skin, tendon, ligament, and cartilage. We investigated the effects of biglycan and decorin on the inhibition of alpha-thrombin by the serine proteinase inhibitor heparin cofactor II. In solution, heparin cofactor II inhibition of thrombin is accelerated by intact biglycan or decorin and by the dermatan sulfate-containing glycosaminoglycan (GAG) chains prepared from the proteoglycans, while core protein from cartilage biglycan had no effect. L-Iduronic acid-rich skin decorin and GAG chains had a greater accelerating effect than proteoglycan and GAG chains from cartilage that had lower L-iduronic acid content. Treatment of skin decorin and GAG chains with chondroitinase ABC totally eliminated the ability of these compounds to accelerate thrombin inhibition by heparin cofactor II suggesting that dermatan sulfate was responsible for this action. Both biglycan and decorin bound to type V collagen in a saturable and specific manner. Biglycan, decorin, and core protein from biglycan competed for decorin binding to the type V collagen, while only the intact proteoglycans competed for biglycan binding. When bound to type V collagen, both biglycan and decorin accelerated the heparin cofactor II/thrombin inhibition reaction as efficiently as the proteoglycans in solution. Our results demonstrate that heparin cofactor II in the presence of biglycan or decorin bound to type V collagen provides a "thromboresistant surface," further suggesting a physiological function for these proteins in regulating the extravascular activities of thrombin.
