In Pathway: L-ascorbate biosynthesis III, 2-keto-L-gulonate biosynthesis

The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the Enzyme Commission system.

Mass balance status: Balanced.

Enzyme Commission Primary Name: L-sorbose 1-dehydrogenase

Enzyme Commission Synonyms: SDH

Enzyme Commission Summary:
The product, L-sorbosone, is an intermediate in bacterial 2-keto-L-gulonic-acid formation. The activity of this membrane-bound enzyme is stimulated by Fe(III) or Co2+ but is inhibited by Cu2+. The enzyme is highly specific for L-sorbose as other sugars, such as glucose, mannitol and sorbitol, are not substrates. Phenazine methosulfate and DCIP can act as artificial acceptors.
