Enzyme Information

1.12.2.1
Cytochrome-c3 hydrogenase.
based on mapping to UniProt P18187
H(2) + 2 ferricytochrome c3 = 2 H(+) + 2 ferrocytochrome c3.
-!- Some forms of the enzyme contain nickel ([NiFe]-hydrogenases) and, of these, some contain selenocysteine ([NiFeSe]-hydrogenases). -!- Methylene blue and other acceptors can also be reduced.
