Chains	Accession	Name	Description	Comments	Source
A	PF07992	Pyridine nucleotide-disulphide oxidoreductase (Pyr_redox_2)	Pyridine nucleotide-disulphide oxidoreductase	This family includes both class I and class II oxidoreductases and also NADH oxidases and peroxidases. This domain is actually a small NADH binding domain within a larger FAD binding domain.	Domain

A	PF00037	4Fe-4S binding domain (Fer4)	4Fe-4S binding domain	Superfamily includes proteins containing domains which bind to iron-sulfur clusters. Members include bacterial ferredoxins, various dehydrogenases, and various reductases. Structure of the domain is an alpha-antiparallel beta sandwich.	Domain
B	PF02754	Cysteine-rich domain (CCG)	Cysteine-rich domain	The key element of this domain is the CX31-38CCX33-34CXXC sequence motif normally found at the C-terminus in archaeal and bacterial Hdr-like proteins [2]. There may be one or two copies, and the motif is probably an iron-sulfur binding cluster. In so ...	The key element of this domain is the CX31-38CCX33-34CXXC sequence motif normally found at the C-terminus in archaeal and bacterial Hdr-like proteins [2]. There may be one or two copies, and the motif is probably an iron-sulfur binding cluster. In some instances one of the cysteines is replaced by an aspartate, and aspartate can in principle also function as a ligand of an iron-sulfur cluster [2]. The entry includes a subunit from heterodisulphide reductase and a subunit from glycolate oxidase (Swiss:P52074) [1] and glycerol-3-phosphate dehydrogenase.	Domain

Coenzyme F420 hydrogenase (EC:1.12.99.1) reduces the low-potential two-electron acceptor coenzyme F420. This family contains the C termini of F420 hydrogenase and dehydrogenase beta subunits [1], [2]. The N terminus of Methanobacterium formicicum formate dehydrogenase beta chain (EC:1.2.1.2, Swiss:P06130) is also a member of this family [3]. This region is often found in association with the 4Fe-4S binding domain, fer4 (Pfam:PF00037).	Domain
