Chains	Enzyme Name	Description	Catalytic Residues
A	alpha-amino-acid esterase M-CSA #666	alpha-amino acid ester hydrolases (AEHs) catalyse the hydrolysis and synthesis of esters and amides with an alpha-amino group. They can be used to acylate a beta-lactam using an ester as acyl donor without cleaving the beta-lactam nuclei, so the enzyme is suitable for generating widely used antibiotics such as ampicillin, amoxicillin, and the cephalosporins, cephadroxil and cephalexin.
