Enzyme Commission Primary Name: methylxanthine N3-demethylase
Enzyme Commission Synonyms: ndmB (gene name)
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -86.867645 [Latendresse13]
Enzyme Commission Summary:
A non-heme iron oxygenase. The enzyme from the bacterium Pseudomonas putida shares an NAD(P)H-FMN reductase subunit with EC 18.104.22.168, methylxanthine N1-demethylase, and has higher activity with NADH than with NADPH [Summers11]. Also demethylates caffeine and theophylline with lower efficiency. Forms part of the degradation pathway of methylxanthines.
