   7.4.2.1 | Ca2+ |
poor stimulatory activity on ATP-binding subunit HisP with a carboxy-terminal extension of 8 amino acids |
246888 |
| 7.4.2.1 | Co2+ |
dimeric ATP-binding subunit HisP with a carboxy-terminal extension of 8 amino acids - Leu-Glu-His-His-His-His-His-His - under optimal conditions hydrolyzes ATP at a rate comparable to that of the intact complex HisQMP2, requires a cation for activity, Co2+ is the best stimulator at 1 mM |
246888 |
| 7.4.2.1 | Mg2+ |
conformational changes within HisP are sensitive to the presence/absence of Mg ions bound to the ATP |
672634 |
| 7.4.2.1 | Mg2+ |
dimeric ATP-binding subunit HisP with a carboxy-terminal extension of 8 amino acids - Leu-Glu-His-His-His-His-His-His - under optimal conditions hydrolyzes ATP at a rate comparable to that of the intact complex HisQMP2, requires a cation for activity, Co2+ and Mn2+ are more effective than Mg2+ |
246888 |
| 7.4.2.1 | Mg2+ |
required for both transport and ATPase activity |
246889 |
| 7.4.2.1 | Mn2+ |
dimeric ATP-binding subunit HisP with a carboxy-terminal extension of 8 amino acids - Leu-Glu-His-His-His-His-His-His - under optimal conditions hydrolyzes ATP at a rate comparable to that of the intact complex HisQMP2, requires a cation for activity, Mn2+ is the best stimulator at concentrations above 1.5 mM |
