Description
Binds heme (iron protoporphyrin IX) and tetrahydrobiopterin. Most of the bacterial and archaeal enzymes consist of only an oxidase domain and function together with bacterial ferredoxins. The enzyme from the Δ-proteobacterium Sorangium cellulosum also includes a reductase domain that binds FAD, FMN and a [2Fe-2S] cluster. The similar enzymes from plants and animals use only NADPH as acceptor (cf. EC 1.14.13.39).
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
nitric oxide synthetase; NO synthase
Reaction
2 L-arginine + 3 NAD(P)H + 3 H+ + 4 O2 = 2 L-citrulline + 2 nitric oxide + 3 NAD(P)+ + 4 H2O (overall reaction); (1a) 2 L-arginine + 2 NAD(P)H + 2 H+ + 2 O2 = 2 Nω-hydroxy-L-arginine + 2 NAD(P)+ + 2 H2O; (1b) 2 Nω-hydroxy-L-arginine + NAD(P)H + H+ + 2 O2 = 2 L-citrulline + 2 nitric oxide + NAD(P)+ + 2 H2O
