2.7.11.14 | Mg2+ |
inhibition at high concentrations |
640699 |
2.7.11.14 | Mg2+ |
actual substrate: Mg-ATP complex, plus activation by free Mg2+-ions |
640703 |
2.7.11.14 | Mg2+ |
inhibitory in excess, presumably by formation of Mg-ATP-Mg |
640703 |
2.7.11.14 | Mg2+ |
the optimum activation is obtained with a 10:1 ratio of Mg2+/ATP |
640703 |
2.7.11.14 | Ca2+ |
Ca2+-dependent phosphorylation of arrestin, Ca2+ concentrations above 0.0025 mM free Ca2+ stimulate, maximal at 0.05 mM Ca2+, Ca2+ may facilitate arrestin-binding to RK, phosphorylation of rhodopsin is not Ca2+-dependent |
