Metals/Ions | Comment | Organism | Structure |
---|---|---|---|
Mg2+ | required | Escherichia coli | |
Mg2+ | Km: 0.42 mM | Escherichia coli | |
Mg2+ | with acetolactate as substrate , Mg2+ is the only divalent metal ion that supports enzyme catalysis | Escherichia coli | |
Mn2+ | activates reaction with 3-hydroxy-3-methyl-2-oxobutanoate, no effect on reaction with acetolactate | Escherichia coli | |
additional information | Mn2+, Co2+, Ni2+, Zn2+, Ca2+, Cu2+ and Co3+ can not substitute for Mg2+ | Escherichia coli |
