Abstract

There are provided processes for carrying out enzymatic reactions, especially processes for the oxidative or reductive transformation of organic compounds catalysed by enzymes, in which the enzymes require a continuing supply of reducing equivalents to regenerate reduced enzyme species in enzymatically active form, and in which the reducing equivalents are derived electrochemically, including electrochemically from molecular hydrogen, the reducing equivalents preferably being passed directly to the enzyme from the cathode of an electrochemical system. The enzyme may comprise an external mono- oxygenase, oxidoreductase, a (de)hydrogenase, nitrogenase, dioxygenase or luciferas. A liquid crystal coated, semi-conductor or hanging mercury drop electrode may be used.
