Chain A,B,C (PHNS_DESFR | P18187)

molecular function
	GO:0051538	3 iron, 4 sulfur cluster binding	Interacting selectively and non-covalently with a 3 iron, 4 sulfur (3Fe-4S) cluster; this cluster consists of three iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands. It is essentially a 4Fe-4S cluster with one iron missing.
	GO:0051539	4 iron, 4 sulfur cluster binding	Interacting selectively and non-covalently with a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
	GO:0047806	cytochrome-c3 hydrogenase activity	Catalysis of the reaction: 2 H2 + ferricytochrome c3 = 4 H+ + ferrocytochrome c3.
	GO:0008901	ferredoxin hydrogenase activity	Catalysis of the reaction: 2 reduced ferredoxin + 2 H+ = 2 oxidized ferredoxin + H2.
	GO:0051536	iron-sulfur cluster binding	Interacting selectively and non-covalently with an iron-sulfur cluster, a combination of iron and sulfur atoms.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0016491	oxidoreductase activity	Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
biological process
	GO:0055114	oxidation-reduction process	A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
cellular component
	GO:0009375	ferredoxin hydrogenase complex	An enzyme complex that catalyzes the oxidation of reduced ferredoxin. Hydrogenase contains iron-sulfur clusters, and some contain nickel; it can use molecular hydrogen for the reduction of a variety of substances.
	GO:0042597	periplasmic space	The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
