Structure Motif Annotation: Mechanism and Catalytic Site Atlas M-CSA Database Homepage Chains Enzyme Name Description Catalytic Residues penicillin amidase (peptidase C59 family)
M-CSA #241 Penicillin V acylase (PVA), isolated from Bacillus sphaericus , catalyses the hydrolysis of penicillin V to 6-aminopenicillanic acid (6-APA) and phenoxyacetic acid. This reaction is commercially important because 6-APA is used in the synthesis of semi-synthetic penicillins. The enzyme undergoes post-translational autocatalytic self-cleavage to produce the mature enzyme. A tripeptide of Met-Leu-Gly is removed to expose the catalytic N-terminal cysteine residue. PVA belongs to the N-terminal nucleophile (Ntn) superfamily.
