Published: March 2014

ABSTRACTMolecular orientation of two aromatic additives in cellulose acetate propionate (CAP) matrix was investigated from orientation birefringence data and an intermolecular orientation correlation represented by nematic interaction (NI) was evaluated. Poly(ethylene terephthalate) (PET) and poly(ethylene naphthalate) (PEN) oligomers with low molecular weight (ca. 400 g mol−1) were used as the additives. The NI strengths of CAP‐PET and CAP‐PEN were determined to be 0.28 ± 0.05 and 0.96 ± 0.15, respectively. In particular, compared with other polymer/polymer and polymer/small additive blends, the NI value in CAP/PEN blend is much stronger and represents the perfect orientation correlation. The strong orientation correlation is possibly due to the rigid naphtalate structure in PEN. Contrary, a relation between birefringence and orientation function for CAP in bulk and blend showed the same trend, suggesting that the orientation behavior of CAP determines the orientation birefringence. As two ester groups in CAP are responsible for birefringence, the alignment of the ester groups is affected by only the main chain orientation. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

Adapter reagents for protein site specific dye labeling
Authors: Thompson Darren A. , Evans Eric G. B. , Kasza Tomas , Millhauser Glenn L. , Dawson Philip E. 
Published: March 2014

ABSTRACTChemoselective protein labeling remains a significant challenge in chemical biology. Although many selective labeling chemistries have been reported, the practicalities of matching the reaction with appropriately functionalized proteins and labeling reagents is often a challenge. For example, we encountered the challenge of site specifically labeling the cellular form of the murine Prion protein with a fluorescent dye. To facilitate this labeling, a protein was expressed with site specific p‐acetylphenylalanine. However, the utility of this acetophenone reactive group is hampered by the severe lack of commercially available aminooxy fluorophores. Here we outline a general strategy for the efficient solid phase synthesis of adapter reagents capable of converting maleimido‐labels into aminooxy or azide functional groups that can be further tuned for desired length or solubility properties. The utility of the adapter strategy is demonstrated in the context of fluorescent labeling of the murine Prion protein through an adapted aminooxy‐Alexa dye. © 2014 Wiley Periodicals, Inc.

Probing and improving student's understanding of protein α‐helix structure using targeted assessment and classroom interventions in collaboration with a faculty community of practice

Published: March 2014

AbstractThe increasing availability of concept inventories and other assessment tools in the molecular life sciences provides instructors with myriad avenues to probe student understanding. For example, although molecular visualization is central to the study of biochemistry, a growing body of evidence suggests that students have substantial limitations in their ability to recognize and interpret basic features of biological macromolecules. In this study, a pre/posttest administered to students at diverse institutions nationwide revealed a robust incorrect idea about the location of the amino acid side chains in the protein α‐helix structure. Because this incorrect idea was present even after a semester of biochemistry instruction at a range of institutions, an intervention was necessary. A community of expert biochemistry instructors collaborated to design two active learning classroom activities that systematically examine α‐helix structure and function. Several participating faculty used one or both of the activities in their classrooms and some improvement of student understanding of this concept was observed. This study provides a model of how a community of instructors can work together using assessment data to inform targeted changes in instruction with the goal of improving student understanding of fundamental concepts. © 2014 by The International Union of Biochemistry and Molecular Biology, 42(3):XXXXX–XXXXX, 2014.

AbstractThreefold intramolecular ring‐closing metatheses of trans‐[MCl2(P{(CH2)mCHCH2}3)2] are effected with Grubbs’ catalyst. Following hydrogenation catalyzed by [RhCl(PPh3)3], the title complexes trans‐[MCl2(P((CH2)n)3P)] (n=2m+2; M/n=Pt/14, 4 c; Pt/16, 4 d; Pt/18, 4 e; Pd/14, 5 c; Pd/18, 5 e) and sometimes isomers partly derived from intraligand metathesis, trans‐[MCl2{P(CH2)n(CH2)n}P(CH2)n)] (4′c–e, 5′e), are isolated. These react with LiBr, NaI, and KCN to give the corresponding MBr2, MI2, and M(CN)2 species (58–99 %). 13C NMR data show that the MX2 moieties rapidly rotate within the diphosphine cage on the NMR timescale, even at −120 °C. The reaction of 4 c and KSCN gives separable Pt(NCS)2 and Pt(NCS)(SCN) adducts (13 c, 28 %; 14 c, 20 %), and those of 4 c,e and Ph2Zn give PtPh2 species (15 c, 61 %; 15 e, 90 %). 13C NMR spectra of 13 c–15 c show two sets of CH2 signals (ca. 2:1 intensity ratios), indicating that MX2 rotation is no longer rapid. Reactions of 4 c or 4′c and excess NaCCH afford the free diphosphines P{(CH2)14}3P (91 %) and (CH2)14P(CH2)14P(CH2)14 (90 %). The latter has been crystallographically characterized as a bis(BH3) adduct. The crystal structures of eight complexes with P(CH2)14P linkages (PtCl2, PtBr2, PtI2, Pt(NCS)2, PtPh2, PdCl2, PdBr2, PdI2) and 15 e have been determined, and intramolecular distances analyzed with respect to MX2 rotation. The conformations of the (CH2)14 moieties and features of the crystal lattices are also discussed.
