6.3.4.4 | Ca2+ | can replace Mg2+ with lower efficiency | Escherichia coli | |
6.3.4.4 | Mg2+ | two Mg2+ ions are required. The first metal ion is coordinated with beta-phosphoryl groups and gamma-phosphoryl groups of GTP to provide an electron sink, and the second one seems to interact with Asp in the enzyme active site. Km for Mg2+: 0.114 mM | Escherichia coli | |
6.3.4.4 | Mn2+ | can replace Mg2+ with lower efficiency | Escherichia coli |
