Staphylococcus aureus is one of the most frequent causes of nosocomial and community-acquired infections, with drug-resistant strains being responsible for tens of thousands of deaths per year. S. aureus sortase A inhibitors are designed to interfere with virulence determinants. We

The gradient for the fragment molecular orbital (FMO) method interfaced with effective fragment potentials (EFP), denoted by FMO∕EFP, was developed and applied to polypeptides solvated in water. The structures of neutral and zwitterionic tetraglycine immersed in water layers of 2.0

Jejunal disappearance rates of glycine (a model for neutral amino acid absorption), triglycine (a model for peptide transport), and tetraglycine (a model for brush-border membrane hydrolysis) were investigated by an in situ perfusion technique before and after 2 wk of
As part of an investigation on the coordination ability of peptides, structural analyses of the solid di-, tri, and tetrapeptides glycyl-glycine (GG), glycyl-glycyl-glycine (GGG), glycyl-glycyl-glycyl-glycine (GGGG), and their protonated hydrochlorides glycyl-glycine.HCl (GGH), glycyl-glycyl-glycine.HCl (GGGH), and glycyl-glycyl-glycyl-glycine.HCl (GGGGH) have been carried

S(IV) (SO(2),HSO(3)(-)andSO(3)(2-)) autoxidation catalyzed by Cu(II)/tetraglycine complexes in the presence of DNA or 2'-deoxyguanosine (dGuo) resulted in DNA strand breaks and formation of 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo), respectively. Ni(II), Co(II) or Mn(II) (1.0x10(-4)M) complexes had much smaller effects. Cu(II)/tetraglycine (1.0x10(-4)M) in the
