L-Sorbose 1-dehydrogenase

-Sorbose 1-dehydrogenase (, SDH) is an enzyme with systematic name -sorbose:acceptor 1-oxidoreductase. This enzyme catalyses the following chemical reaction


 * -sorbose + acceptor $$\rightleftharpoons$$ 1-dehydro-L-sorbose + reduced acceptor

The product, -sorbosone, is an intermediate in bacterial 2-keto-L-gulonic-acid formation. Co2+ stimulate activity of this membrane-bound enzyme, while Cu2+ act as an inhibitor.
