penicillinase [pen″ĭ-sil´ĭ-nās] an enzyme produced by certain bacteria that inactivates penicillin, so that such bacteria have increased resistance to the antibiotic; a purified form from Bacillus cereus is used in treatment of reactions to penicillin.pen·i·cil·li·nase (pen'i-sil'i-nās), 1. Synonym(s): β-lactamase2. A purified enzyme preparation obtained from cultures of a strain of Bacillus cereus; formerly used to treat slowly developing or delayed penicillin reactions. penicillinase (pĕn′ĭ-sĭl′ĭ-nās′)n. Any of several beta-lactamase enzymes that cleave the beta-lactam ring in penicillins. Penicillinases are found in many penicillin-resistant bacteria.penicillinase An enzyme present in some bacteria, especially STAPHYLOCOCCI, that inactivates penicillins, by HYDROLYSIS of the beta-lactam bond, so that the organisms possess resistance to the drug. Also known as beta-lactamase.be·ta-lac·ta·mase (bā'tă lak'tā-mās) An enzyme produced by many species of bacteria that disrupts the four-membered β-lactam ring of penicillin and cephalosporin groups of antibiotics, destroying their antimicrobial activity.
