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 found in rubredoxin reductase (RdxR) present in Pseudomonas aeruginosa. RdxR are important in prokaryotes as they allow for the metabolism of inert n-alkanes and RdxR is also crucial for archaea and anaerobic bacteria in the response to oxidative stress. This domain is known to recognise and bind to rubredoxin [1].	Domain
