Mycothiol-dependent formaldehyde dehydrogenase

In enzymology, a mycothiol-dependent formaldehyde dehydrogenase is an enzyme that catalyzes the chemical reaction:
The two substrates of this enzyme are S-(hydroxymethyl)mycothiol and oxidised nicotinamide adenine dinucleotide. Its products are S-formylmycothiol, reduced NADH, and a proton.
The enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is formaldehyde:NAD+ oxidoreductase . This enzyme is also called NAD/factor-dependent formaldehyde dehydrogenase or S-mycothiol dehydrogenase.
