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
