Quantitative structure-activityrelationships (QSAR) of N-Ac amino acids, N-Ac dipeptides, and N-Ac tripeptides in inhibition of 125I-labeled ristocetin binding to Micrococcus luteus cell wall have been developed to probe the details of the binding between ristocetin and N-acetylated peptides. The correlationequations indicate that (1) the binding is stronger for peptides in which the side chain of

Peptide bond formation by aminolysin-A catalysis: A simple approach to enzymatic synthesis of diverse short oligopeptides and biologically active puromycins
peptide bonds to give linear homo-oligopeptides, hetero-dipeptides, and cyclicdipeptides using cost-effective substrates in a one-pot reaction. Aminolysin-A can recognize several C-terminal-modified aminoacids, including the L- and D-forms, as acyl donors as well as free amines, including aminoacids and puromycin aminonucleoside, as acyl acceptors. The absence of aminoacid esters prevents the formation

in solidstate under heating was studied. The change in morphology of dipeptide thin film and formation of nanostructures after heating was visualized using atomic force microscopy. This method also was used for demonstration of differences in self-assembly of linear and cyclic dipeptides. The chemical structure of reaction product was characterized by NMR spectrometry, FTIR spectroscopy and GC–MS analysis
