Hydrogenase (acceptor)

In enzymology, a hydrogenase (acceptor) (EC 1.12.99.6) is an enzyme that catalyzes the chemical reaction

H₂ + A ${\displaystyle \rightleftharpoons }$ AH₂

Thus, the two substrates of this enzyme are H₂ and A, whereas its product is AH₂.

This enzyme belongs to the family of oxidoreductases, specifically those acting on hydrogen as donor with other acceptors. The systematic name of this enzyme class is hydrogen:acceptor oxidoreductase. Other names in common use include H2 producing hydrogenase[ambiguous], hydrogen-lyase[ambiguous], hydrogenlyase[ambiguous], uptake hydrogenase[ambiguous], and hydrogen:(acceptor) oxidoreductase.
