Bicelles as model membranes for solid‐ and solution‐state NMR studies of membrane peptides and proteins
Authors: Marcotte Isabelle , Auger Michèle
Published: January 2005

Bicelles are an attractive membrane mimetic system because of their planar surface and lipid composition, which resemble biological membranes. In addition, their orientation and morphologic properties make them amenable to solid‐ and solution‐state NMR. This article reviews the physical properties of bicelles, such as magnetic alignment and viscosity as well as the different models proposed in the literature to explain the bicelle morphology. The utility of bicelles for studying the interaction and structure of membrane peptides and proteins by solid‐ and solution‐state NMR is also presented, along with the advantages and limitations of bicelles. © 2005 Wiley Periodicals, Inc.

The concept of effective correlation times for describing backbone motions in proteins. Part I. A residue‐per‐residue self‐consistent analysis of multifield 15N relaxation parameters
Authors: Bouguet‐Bonnet Sabine , Mutzenhardt Pierre , Roumestand Christian , Canet Daniel
Published: January 2005

This study is an extension of a recent work (Canet D, Barthe P, Mutzenhardt P, Roumestand C. 2001. A comprehensive analysis of multifield 15N relaxation parameters in proteins: Determination of 15N chemical shift anisotropies. J Am Chem Soc 123:4567–4576) dealing with the exploitation of the three classical 15N relaxation parameters (the longitudinal relaxation rate, R1, the transverse relaxation rate, R2, and the 1H‐15N cross‐relaxation rate, σNH) measured at several magnetic fields (at least two) in uniformly 15N‐labeled proteins (the chosen example is the C12A‐p8MTCP1 protein whose relaxation parameters have been measured at five different fields). R2 is iteratively corrected for exchange, so that the three parameters provide consistently the NH dipolar and 15N csa (chemical shift anisotropy) contributions. The dipolar spectral densities are analyzed, residue by residue, according to the functional form $$a_d + { b_d \over {1 + \omega^{2}\tau^{2}_{e\!f\!f}}}$$ (d for dipolar), where τeff is an (effective) correlation time associated with the slow motion(s) sensed by the NH vector at the level of the residue to which it belongs. In comparison with the Lipari‐Szabo approach, the coefficient bd can be identified with 2KdτeffS2, S being the generalized order parameter and Kd reflecting the amplitude of the dipolar mechanism (which, besides constants, involves $$1/r^{6}_{NH}$$); ad is associated with fast local motions. The csa spectral densities appearing in the expressions of R1 and R2 can be analyzed according to $${b_{csa\hphantom{j}}} \over {1 + \omega^{2}\tau^{2\hphantom{T}}_{e\!f\!\!f}}$$; bcsa; is proportional to bd (the proportionality factor depending on molecular quantities) and can yield 15N csa values from the rNH value and from the knowledge of the angle between the two relevant tensors. Uncertainties are such that it is impossible (at least with the present data) to conclude about a possible variation of 15N csa values along the protein backbone. © 2005 Wiley Periodicals, Inc.

Synthesis of Chiral, Half‐Sandwich Ruthenium Complexes from Weakly Coordinated Solvent Species
Authors: Jekki Laetitia , Pala Corinne , Calmuschi Beatrice , Ganter Christian
Published: January 2005

The bis(acetonitrile) species 7 has been synthesized in a multistep protocol. This chiral phosphaferrocene‐containing, half‐sandwich ruthenium complex easily provides two coordination sites due to the high lability of the coordinated solvent molecules. Although complex 7 could not be isolated in pure form, it serves as a valuable starting material for the preparation of other half‐sandwich complexes with, for example, pyridine (8), tmeda (9), N‐(2‐dimethylaminoethyl)‐morpholine (10), or tricyclohexylphosphine (11) as ligands. Whereas the morpholine complex 10 was obtained as almost a 1:1 mixture of diastereomers, the mixed MeCN/PCy3 complex 11 was formed with a high level of diastereoselectivity (90% de). The molecular structures of complexes 8, 10, and the cyclopentadiene derivative 3a were determined by X‐ray diffraction. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
Mono‐, Di‐ and Polymeric Calcium and Gadolinium Complexes of the Tripodal Ligand 2,2′,2′′‐Nitrilotribenzoic Acid
Authors: Wörl Stefan , Fritsky Igor O. , Hellwinkel Dieter , Pritzkow Hans , Krämer Roland
Published: January 2005

Three novel carboxylate‐bridged complexes incorporating the tripodal N,O ligand 2,2′,2′′‐nitrilotribenzoic acid H3L of formula [CaII(H2L)(OH2)4][(H2L)]·4H2O (1), [CaII(OH2)4]‐[CaII(L)(OH2)2]2·7H2O (2) and [GdIII(L)(OH2)3]2[GdIII(L)‐(OH2)4]2·13H2O (3) were synthesized and characterized by X‐ray crystallography. In all three complexes, the ligand H3L binds to the metal centre only by its three carboxylate donors, leaving the bridgehead nitrogen atom nonbonding. The calcium(II) ion in the monomeric complex 1 is distorted pentagonal‐bipyramidal coordinated, the +1 charge of the complex cation [CaII(H2L)(OH2)4]+ is balanced by an H2L– anion and both units are connected by hydrogen bonds. The polymeric compound 2 displays a one‐dimensional chain structure, in which two [CaII(L)]2– units form a dimeric structure and are connected by hydrated CaII ions. 3 contains two different [GdIII(L)(OH2)n] dimers. In one of them the two GdIII ions are linked by two monoatomic carboxylate O‐bridges showing a short Gd···Gd distance of 3.99 Å. In the second, a syn‐anti carboxylate 1,3‐bridge with a longer Gd···Gd distance of 4.96 Å is observed. Magnetic measurements of 3 show paramagnetic behaviour with weak antiferromagnetic coupling.

The Reactions of Elemental Iron with Dipicolinic Acid (H2dipic) and Quinaldic Acid (Hquin) – X‐ray Crystal Structures of [C5H5NH][Fe(Dipic)(Hdipic)(C5H5N)2]·3C5H5N, [Fe2(µ‐O)(Dipic)2(C5H5N)4]·2C5H5N·2H2O and trans‐[Fe(Quin)2(MeOH)2]
Authors: Jain Sneh L. , Slawin Alexandra M. Z. , Derek Woollins J. , Bhattacharyya Pravat
Published: January 2005

Iron powder reacts with dipicolinic acid (H2dipic) in pyridine at 110 °C to give the heptacoordinate iron(II) complex [C5H5NH][Fe(dipic)(Hdipic)(C5H5N)2]; the (Hdipic)– ligand binds to the metal centre solely through the oxygen atoms of one carboxylate group, the first example of this coordination mode at iron. Upon dissolution in pyridine under aerobic conditions this complex transforms into the oxo‐bridged diiron(III) species [Fe2(μ‐O)(dipic)2(C5H5N)4], which possesses a linear Fe–O–Fe axis. Quinaldic acid (Hquin) reacts withiron powder in pyridine at 110 °C to give [Fe(quin)2(C5H5N)2],analogous to the corresponding reactivity of picolinic acid. This complex is converted into trans‐[Fe(quin)2(MeOH)2] or [Fe2(μ‐O)(quin)4(dmf)2] in methanol or DMF respectively. The formation of an iron(II) complex in the reaction with methanol differs markedly from the picolinate system. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
