Activating Compound

Activating Compound Comment Organism Structure
catalase increases pMMO activity, catalyzes decomposition of H2O2, on pMMO activity Methylosinus trichosporium OB3b

Inhibitors

Inhibitors Comment Organism Structure
H2O2 reversible inhibition of pMMO with H2O2 upon treatment of pMMO with H2O2 followed by the addition of catalase. H2O2 re-oxidizes the type 2 copper in pMMO reduced with duroquinol Methylosinus trichosporium OB3b
