A mutant of Bacillus cereus 5/B, strain 5/B/6, produces a beta-lactamase II-like enzyme but no beta-lactamase I. Beta-lactamases II and II 5/B/6 appear to show a high degree of homology, but there are significant differences in their enzymic properties.
蜡样芽孢杆菌5/B的突变株5/B/6产生一种类β-内酰胺酶II,但不产生β-内酰胺酶I。β-内酰胺酶II和5/B/6的β-内酰胺酶II似乎具有高度同源性,但其酶学性质存在显著差异。
