某些金属离子对ATP水解有催化作用,但这种催化作用一般不大,而个别金属离子被氧化时,与它络合着的ATP水解速度则大大提高,ATP的水解与络离子的电子输出可以认为是偶联着进行的。Haight等所发现的VO~(2+)-三聚磷酸盐-H_2O_2体系和Mn~(2+)-三聚磷酸盐-MnO_4~-体系的行为即为已知的少数例子。对于过渡金属原子簇化 Some metal ions catalyze the hydrolysis of ATP, but this kind of catalysis is generally not large. However, when individual metal ions are oxidized, the hydrolysis rate of ATP complexed with it is greatly increased. The hydrolysis of ATP and the electron output of complex ions Can be considered coupled. The behavior of the VO ~ (2 +) - tripolyphosphate-H 2 O 2 system and the Mn 2+ (2 +) - tripolyphosphate -MnO 4 ~ system found by Haight et al. Is known as a few examples. For transition metal cluster
