DEFINITION

Classification: 435/230

Penicillin amidase:

(under subclass 228) Subject matter wherein the enzyme catalyzes the hydrolysis of pencillin forming a carboxylic acid anion and penicin.

(1) Note. Penicillin amidase (acylase) also acts in the reverse direction producing penicillins from 6-aminopenicillanic acid and a appropriate side chain.
