CRYSTAL STRUCTURE OF NITRIC REDUCTASE FROM DENITRIFYING FUNGUS FUSARIUM OXYSPORUM COMPLEX WITH CARBON MONOXIDECRYSTAL STRUCTURE OF NITRIC REDUCTASE FROM DENITRIFYING FUNGUS FUSARIUM OXYSPORUM COMPLEX WITH CARBON MONOXIDE
Structural highlights
Function[NOR_FUSOX] Nitric oxide reductase which is involved in a dissimilatory reduction of nitrite. Acts as a nitric oxide reductase. Is able to reduce nitrate and nitrite to a gaseous form of N(2)O when oxygen supply is limited or discontinued. May function as a detoxification mechanism.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedStructures of nitric oxide reductase (NOR) in the ferric resting and the ferrous CO states have been solved at 2.0 A resolution. These structures provide significant new insights into how NO is reduced in biological systems. The haem distal pocket is open to solvent, implicating this region as a possible NADH binding site. In combination with mutagenesis results, a hydrogen-bonding network from the water molecule adjacent to the iron ligand to the protein surface of the distal pocket through the hydroxyl group of Ser 286 and the carboxyl group of Asp 393 can be assigned to a pathway for proton delivery during the NO reduction reaction.
