Methanethiol oxidase explained

methanethiol oxidase
Ec Number:1.8.3.4
Cas Number:112821-28-0
Go Code:0018549

In enzymology, a methanethiol oxidase is an enzyme that catalyzes the chemical reaction

methanethiol + O2 + H2O

\rightleftharpoons

formaldehyde + hydrogen sulfide + H2O2

The 3 substrates of this enzyme are methanethiol, O2, and H2O, whereas its 3 products are formaldehyde, hydrogen sulfide, and H2O2.[1]

This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with oxygen as acceptor. The systematic name of this enzyme class is methanethiol:oxygen oxidoreductase. Other names in common use include methylmercaptan oxidase, methyl mercaptan oxidase, (MM)-oxidase, and MT-oxidase.
