Abstract
A wild strain of Staphylococcus aureus which inactivates a wide variety of antibiotics has been found to inactivate pristinamycin IIA, an antistaphylococcal antibiotic. This phenomenon has been demonstrated to be plasmid mediated. The plasmid directs the biosynthesis of an acetyltransferase which is able to O-acetylate the drug. We propose to call the new enzyme PAC (IIA): Pristinamycin acetyltransferase.
摘要
已发现一种能使多种抗生素失活的金黄色葡萄球菌野生菌株可使抗葡萄球菌抗生素普那霉素IIA失活。这种现象已被证明是由质粒介导的。该质粒指导一种乙酰转移酶的生物合成，这种乙酰转移酶能够将药物进行O-乙酰化。我们提议将这种新酶称为PAC（IIA）：普那霉素乙酰转移酶。
