We examined the similarities and differences between the activities of N-succinyl-LL-diaminopimelate aminotransferase (DAP-AT) and N-acetylornithine aminotransferase (NAcO-AT) from E. coli and M. smegmatis in order to investigate recent claims that the two enzymes are one and the same. The results do not support the hypothesis that the two activities are catalysed by a single enzyme.
我们检查了大肠杆菌和耻垢分枝杆菌中的 N-琥珀酰-LL-二
氨基
庚二酸转
氨酶 (DAP-AT) 和 N-乙酰
鸟氨酸转
氨酶 (NAcO-AT) 活性之间的异同,以调查最近关于这两种物质的说法。酶是同一种酶。结果不支持这两种活性由单一酶催化的假设。
