1MPX - PubMed Abstract: 
alpha-Amino acid ester hydrolases (AEHs) catalyze the hydrolysis and synthesis of esters and amides with an alpha-amino group. As such, they can synthesize beta-lactam antibiotics from acyl compounds and beta-lactam nuclei obtained from the hydrolysis of natural antibiotics ...
