Valine dehydrogenase (NAD+)

Valine dehydrogenase (NAD+) is an enzyme with systematic name L-valine:NAD+ oxidoreductase (deaminating). This enzyme catalyses the following chemical reaction


 * L-valine + H2O + NAD+ $$\rightleftharpoons$$ 3-methyl-2-oxobutanoate + NH3 + NADH + H+

The enzyme from Streptomyces spp. has no activity with NADP+.
