    6.1.1.4 | Al3+ |
accelerates reaction |
442 |
| 6.1.1.4 | Ba2+ |
Mg2+, Mn2+, Ca2+ and Ba2+ similarly effective, optimal concentration: 0.1 mM |
424 |
| 6.1.1.4 | Ca2+ |
75% of the maximal activity obtained with Mg2+ |
432 |
| 6.1.1.4 | Ca2+ |
can partially replace Mg2+ in activation (in chloroplastic enzyme, not in cytoplasmic enzyme) |
432, 436 |
| 6.1.1.4 | Ca2+ |
Mg2+, Mn2+, Ca2+ and Ba2+ similarly effective, optimal concentration: 0.1 mM |
424 |
| 6.1.1.4 | Co2+ |
40% of the maximal activity obtained with Mg2+ |
432 |
| 6.1.1.4 | Co2+ |
can partially replace Mg2+ in activation (in chloroplastic enzyme, not in cytoplasmic enzyme |
432, 436 |
| 6.1.1.4 | Fe2+ |
accelerates reaction |
442 |
| 6.1.1.4 | Fe3+ |
accelerates reaction |
442 |
| 6.1.1.4 | K+ |
30 mM KCl enhance activity of cytoplasmic enzyme, no effect on chloroplastic enzyme, concentrations higher than 30 mM inhibit cytoplasmic enzyme more strongly than chloroplastic enzyme |
436 |
