Metals/Ions Comment Organism Structure
Ca2+ pyrroloquinoline quinone is bound at the active site via a Ca2+ bridge, enzyme contains 1.95 mol of Ca2+ per mol of subunit Acinetobacter calcoaceticus
Ca2+ Ca2+ is required for reactivation after thermal inactivation Acinetobacter calcoaceticus
Cd2+ can replace Ca2+ in reactivation after thermal inactivation Acinetobacter calcoaceticus
Mn2+ can replace Ca2+ in reactivation after thermal inactivation Acinetobacter calcoaceticus
