Ligands: GOL Activity: Nitrite reductase (NAD(P)H), with EC number 1.7.1.4 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Publication Abstract from PubMed NirD is part of the nitrite reductase complex NirBD that catalyses the reduction of nitrite to NH(3) in nitrate assimilation and anaerobic respiration. The crystal structure analysis of NirD from Mycobacterium tuberculosisshows a double?beta-sandwich fold. NirD is related in three-dimensional structure and sequence to the Rieske proteins, however it does not contain any Fe-S cluster or other cofactors that might be involved in electron transfer. A cysteine residue at the protein surface, conserved in NirD homologues lacking the iron- sulfur cluster might be important for the interaction with NirB, and possibly stabilize one the Fe-S centers in this subunit.
