References of beta-Lactamase
Title: Penicillinase
CAS Registry Number: 9001-74-5
Synonyms: b-Lactamase
Trademarks: Neutrapen (3M Pharma)
Literature References: Mol wt about 50,000. Enzymes found in many bacteria which destroy penicillins and cephalosporins by catalyzing the hydrolysis of the amide bond in the b-lactam ring. Good penicillinase producers are Bact. coli, the Bacillus subtilis-mesentericus group, Bacillus anthracis and Staphylococci. Both intra- and extracellular penicillinase are of protein nature. There are probably as many different penicillinases as there are bacteria producing them.
