Nitric oxide synthase:
Ans. D. Requires NADPH FAD, FMN, Heme ironNitric oxide synthase is a very complex cytosolic enzyme which requires five redox co-factors: NADPH, FAD, FMN, Heme and tetrahydrobiopterin (FH4 ). NOS activity depends on increased conc, of Ca2++ ions.
Is inhibited by Ca++
Catalyze a de oxygenase reaction
Accept electron from NADH.
Requires NADPH FAD, FMN, Heme iron.
