Mycothione reductase

In enzymology, a mycothione reductase is an enzyme that catalyzes the chemical reaction


 * 2 mycothiol + NAD(P)+ $$\rightleftharpoons$$ mycothione + NAD(P)H + H+

The 3 substrates of this enzyme are mycothiol, NAD+, and NADP+, whereas its 4 products are mycothione, NADH, NADPH, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is mycothiol:NAD(P)+ oxidoreductase. This enzyme is also called mycothiol-disulfide reductase.
