<b>概述：</b><span>青霉素酶（</span>Penicillinase<span>）又称</span><span>I</span><span>型</span><span>β-</span><span>内酰胺酶（</span><span>β-lactamase type I</span><span>，</span><span>EC 3.5.2.6</span><span>），可水解</span><span>β-</span><span>内酰胺类抗生素的</span><span>β-</span><span>内酰胺环，从而使其失去抗微生物活性。本品是采用基因工程技术获得的重组</span>无菌<span>青霉素酶，通过构建青霉素酶高效表达工程菌株和发酵纯化获得高纯度、活性高产品。产品具有专一性强的特点。可有效水解</span><span>β-</span><span>内酰胺类抗生素，包括青霉素</span><span>G</span><span>、氨苄青霉素、氨苄西林、阿莫西林、匹氨西林、羧苄西林、替卡西林、呋苄西林、美洛西林等。</span>
