Mg2+ | 10 mM, 65% of the activity with Mn2+ | Homo sapiens | |
Mn2+ | divalent cation is essential for enzyme from gastric mucosa, maximal activity with 10 mM Mn2+. Enzyme from plasma is maximally activated with 10 mM Mn2+, but activity is also observed without the cation | Homo sapiens | |
Mn2+ | 10 mM, best activator | Homo sapiens | |
additional information | divalent cation is absolutely required, no activation with Zn2+ | Homo sapiens |
