A, B [auth D], C [auth G], D [auth J]	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

This C-terminal domain appears to be a dimerisation domain of the mitochondrial apoptosis-inducing factor 1. protein. The domain also appears at the C-terminus of FAD-dependent pyridine nucleotide-disulfide oxidoreductases. Apoptosis inducing factor (AIF) is a bifunctional mitochondrial flavoprotein critical for energy metabolism and induction of caspase-independent apoptosis. On reduction with NADH, AIF undergoes dimerisation and forms tight, long-lived FADH2-NAD charge-transfer complexes proposed to be functionally important.	Domain
