Influence of Heme-Thiolate in Shaping the Catalytic Properties of a Bacterial Nitric-oxide Synthase

Nitric-oxide synthases (NOS) are heme-thiolate enzymes that generate nitric oxide (NO) from l-arginine. Mammalian and bacterial NOSs contain a conserved tryptophan (Trp) that hydrogen bonds with the heme-thiolate ligand. We mutated Trp(66) to His and Phe (W66H, W66F) in B. subtilis NOS to investigat...
