Chains	Enzyme Name	Description	Catalytic Residues
B	xanthine dehydrogenase (bacterial) M-CSA #698	Rhodobacter capsulatus xanthine dehydrogenase (RcXDH), a cytoplasmic enzyme, catalyses the hydroxylation of a wide variety of purine, pyrimidine, pterin, and aldehyde substrates. Oxidation of the substrate occurs in the molybdenum centre, and the reduced enzyme is reoxidised by the oxidant substrate, NAD+ or molecular oxygen, through FAD. The cofactors of this enzyme are located on different polypeptides. The FAD and the two different [2Fe-2S] iron-sulphur clusters are found on the XDHA subunit, while the molybdenum cofactor (Moco), with a bicyclic pterin and monocyclic pyran coordinated to it, is bound to the XDHB subunit.
