Methanol dehydrogenase
From Wikipedia, the free encyclopedia
In enzymology, a methanol dehydrogenase (MDH) is an enzyme that catalyzes the chemical reaction:
- CH3OH
CH2O + 2 electrons + 2H+

How the electrons are captured and transported depends upon the kind of methanol dehydrogenase. There are three main types of MDHs: NAD+-dependent MDH, pyrrolo-quinoline quinone dependent MDH, and oxygen-dependent alcohol oxidase.[2]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is methanol:NAD+ oxidoreductase. This enzyme participates in methane metabolism.
