Chains	Accession	Name	Description	Comments	Source
C	PF02817	e3 binding domain (E3_binding)	e3 binding domain	This family represents a small domain of the E2 subunit of 2-oxo-acid dehydrogenases responsible for the binding of the E3 subunit.	Domain
A, B	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, B	PF02852	Pyridine nucleotide-disulphide oxidoreductase, dimerisation domain (Pyr_redox_dim)	Pyridine nucleotide-disulphide oxidoreductase, dimerisation domain	This family includes both class I and class II oxidoreductases and also NADH oxidases and peroxidases.	Domain
