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

This is the C-terminal domain of NADH rubredoxin oxidoreductase present in Clostridium acetobutylicum. The majority of obligatory anaerobes detoxify micro-aerobic environments by consuming O2 via H2O-forming NADH oxidase. This enzyme offers an alternate reaction pathway for scavenging of O2 and reactive oxygen species, wherein the reducing equivalent is obtained from NADH [1].	Domain
