The present invention relates to an enzyme and method for the hydroxylation of a 7-deoxysteroid having the general formula (I)

Method for the hydroxylation of steroids

A process for the enzymatic regeneration of the redox cofactors NAD/NADH and NADP/NADPH in a one-pot reaction, wherein, as a result of at least two further enzymatically catalyzed redox reactions proceeding in the same reaction batch (product-forming reactions), one of the two redox cofactors accumulates in its reduced form and, respectively, the other one in its oxidized form, characterized in that a) in the regeneration reaction which reconverts the reduced cofactor into its original oxidized form, oxygen or a compound of general formula RC(O)COOH is reduced, and b) in the regeneration reaction which reconverts the oxidized cofactor into its original reduced form, a compound of general formula RCH(OH)Ris oxidized and wherein R, Rand Rin the compounds have different meanings.

Process for the enzymatic regeneration of redox cofactors

The present invention relates to a process for the conversion of D-glucose. The process according to the invention comprises a step a) in which part of the D-glucose is enzymatically oxidized to D-gluconic acid (lactone) and a portion of the D-glucose which is essentially equimolar thereto is reduced to D-sorbitol. In addition to D-glucose, D-fructose is also present in the reaction mixture of step a). The process comprises a further step b) in which D-sorbitol formed from the D-glucose in step a) is enzymatically oxidized to D-fructose.
