Mg2+ | with exogenous substrate maximal activity is obtained at 5 mM Mg2+. Maximal phosphorylation of endogenous substrate is in shoot plasma membranes at around 12.5 mM Mg2+. In root membranes 5-40 mM Mg2+ stimulate the phosphorylation of the endogenous substrate | Triticum aestivum | |
Mn2+ | stimulatory effect of Mg2+ can only be partly substituted by Mn2+ | Triticum aestivum |
