Reaction: H2 + 2 oxidized ferredoxin = 2 reduced ferredoxin + 2 H+
Other name(s): H2 oxidizing hydrogenase; H2 producing hydrogenase [ambiguous]; bidirectional hydrogenase; hydrogen-lyase [ambiguous]; hydrogenase (ferredoxin); hydrogenase I; hydrogenase II; hydrogenlyase [ambiguous]; uptake hydrogenase [ambiguous]
Systematic name: hydrogen:ferredoxin oxidoreductase
Comments: Contains iron-sulfur clusters. The enzymes from some sources contains nickel. Can use molecular hydrogen for the reduction of a variety of substances. Formerly EC 1.12.1.1, EC 1.12.7.1, EC 1.98.1.1, EC 1.18.3.1 and EC 1.18.99.1.
