Methanethiol oxidase

From Wikipedia, the free encyclopedia

In enzymology, a methanethiol oxidase (EC 1.8.3.4) is an enzyme that catalyzes the chemical reaction

methanethiol + O₂ + H₂O 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.

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.
