DE   L-sorbose 1-dehydrogenase.
AN   SDH.
CA   L-sorbose + acceptor = 1-dehydro-L-sorbose + reduced acceptor.
CC   -!- The product, 1-dehydro-L-sorbose, is an intermediate in bacterial
CC       2-keto-L-gulonic-acid formation.
CC   -!- The activity of this membrane-bound enzyme is stimulated by Fe(III)
CC       or Co(2+) but is inhibited by Cu(2+).
CC   -!- Highly specific for L-sorbose as other sugars, such as glucose,
CC       mannitol and sorbitol, are not substrates.
CC   -!- Phenazine methosulfate and DCIP can act as artificial acceptors.
