The crystal structures of the complexes of oxalic acid with glycyl-L-histidine and L-histidyl-L-alanine were determined. The three crystallographically independent peptide molecules in the complexes have closed conformations. The terminal carboxyl group of the dipeptide and the oxalate ion in the

Monocationic gold(III) complexes with histidine-containing peptides, glycyl-L-histidine (Gly-L-His) and L-alanyl-L-histidine (L-Ala-L-His) have been synthesized and characterized by (1)H NMR spectroscopy and X-ray crystallography. The crystallized Au(III) complexes, [Au(Gly-L-His-N,N',N'')Cl]NO(3)·1.25H(2)O and [Au(L-Ala-L-His-N,N',N'')Cl]NO(3)·2.5H(2)O, were obtained from water solution at pH < 1.0. The
A glycine-histidine tag (Gly3His6) was added to the C-terminus of a fusion protein consisting of the cholera toxin B-subunit (CtxB) and the IgA protease beta-domain (Iga beta). The aim was to facilitate single-step purification and to create a suitable tool
Knowledge of the complexes formed by N-coordinating ligands and Cu(II) ions is of relevance in understanding the interactions of this ion with biomolecules. Within this framework, we investigated Cu(II) complexation with mono- and polydentate ligands, such as ammonia, ethylenediamine (en)
Structural analysis of recombinant fibrinogen fragment D revealed that the calcium-binding site (beta2-site) composed of residues BbetaAsp261, BbetaAsp398, BbetaGly263, and gammaGlu132 is modulated by the "B:b" interaction. To determine the beta2-site's role in polymerization, we engineered variant fibrinogen gammaE132A in
