Fe2+
-
one mole per mole enzyme, activation of enzyme with 0.5 mM FeSO4 for 15 min at 25°C, replacement with other divalent cations do not lead to detectable 2,5-dihydroxypyridine dioxygenase activity
Fe2+
-
purified enzyme is inactive, Fe2+-dependent reactivation of the purified enzyme (0.025 mM), 0.0198 mM iron is detected, indicating that the ratio of mol of iron to mol of a monomer of NicX is near 1.0
Fe2+
the enzyme uses a mononuclear non-heme iron enzyme to catalyze the oxidative pyridine ring cleavage reaction
