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	PF22353	NAD(P)H:rubredoxin oxidoreductase, C-terminal domain (PF1197-like_C)	NAD(P)H:rubredoxin oxidoreductase, C-terminal domain	This domain is found at the C-terminal end of NAD(P)H:rubredoxin oxidoreductase from Pyrococcus furiosus (PF1197) and similar sequences mainly found in archaea.

This domain is found at the C-terminal end of NAD(P)H:rubredoxin oxidoreductase from Pyrococcus furiosus (PF1197) and similar sequences mainly found in archaea. PF1197 catalyses the NADH -dependent reduction of rubredoxin (Rd), a small iron -containing redox protein. This domain, likely to be involved in dimerisation, is often found associated with Pfam:PF07992.	Domain
