| hcp | norV | STM0937 | STM2840 | Hybrid cluster protein; Catalyzes the reduction of hydroxylamine to form NH(3) and H(2)O. | Putative flavoprotein; Anaerobic nitric oxide reductase; uses NADH to detoxify nitric oxide (NO), protecting several 4Fe-4S NO-sensitive enzymes. Has at least 2 reductase partners, only one of which (NorW, flavorubredoxin reductase) has been identified. NO probably binds to the di-iron center; electrons enter from the NorW at rubredoxin and are transferred sequentially to the FMN center and the di-iron center. Also able to function as an aerobic oxygen reductase; In the N-terminal section; belongs to the zinc metallo- hydrolase group 3 family. | 0.903 |
