enzyme Name penicillin amidase EC number 3.5.1.11 CAS number 9014 06 6 IUBMB EC number 3 5 1 11 GO code 0008953 image width caption In enzymology , a penicillin amidase EC number 3.5.1.11 is an enzyme that catalysis catalyzes the chemical reaction penicillin H sub 2 sub O math rightleftharpoons math a carboxylate 6 aminopenicillanate Thus, the two substrate biochemistry substrates of this enzyme are penicillin and water H sub 2 sub O , whereas its two product chemistry products are carboxylate and 6 aminopenicillanate . This enzyme belongs to the family of hydrolase s, those acting on carbon nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is penicillin amidohydrolase . Other names in common use include penicillin acylase , benzylpenicillin acylase , novozym 217 , semacylase , alpha acylamino beta lactam acylhydrolase , and ampicillin acylase . This enzyme participates in penicillin and cephalosporin biosynthesis .

The protein transpeptidase is also known as Novel penicillin binding protein, which is necessary for cell wall peptidoglycan formation, and is inhibited by penicillin. The antibiotic penicillin irreversibly binds to and inhibits the activity of the transpeptidase enzyme by forming a highly stable penicilloyl enzyme intermediate.
