Flavin reductase (NADH)

Flavin reductase (NADH) (, NADH-dependent flavin reductase, flavin:NADH oxidoreductase) is an enzyme with systematic name flavin:NAD+ oxidoreductase. This enzyme catalyses the following chemical reaction


 * reduced flavin + NAD+ $$\rightleftharpoons$$ flavin + NADH + H+

The Escherichia coli enzyme reduces free flavins by NADH.
