CAS编号
Comments A non-heme iron oxygenase. The enzyme from the bacterium Pseudomonas putida shares an NAD(P)H-FMN reductase subunit with EC 1.14.13.179, methylxanthine N3-demethylase, and has a 5-fold higher activity with NADH than with NADPH [2]. Also demethylate 1-methylxantine with lower efficiency. Forms part of the degradation pathway of methylxanthines.
Cofactor Fe cation
History
Reactions (1) Caffeine + O(2) + NAD(P)H = theobromine + NAD(P)(+) + H(2)O + formaldehyde. (2) Theophylline + O(2) + NAD(P)H = 3-methylxanthine + NAD(P)(+) + H(2)O + formaldehyde. (3) Paraxanthine + O(2) + NAD(P)H = 7-methylxanthine + NAD(P)(+) + H(2)O + formaldehyde.
