Mycothione reductase
In enzymology, a mycothione reductase is an enzyme that catalyzes the chemical reaction
in M. tuberculosis and other actinomycetes.
The 2 substrates of this enzyme are mycothiol and NADPH, whereas 2 molecules of mycothione and NADP+ are formed as products.
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+ oxidoreductase. This enzyme is also called mycothiol-disulfide reductase.
