Nitric oxide (NO) is synthesised from l-arginine by the enzyme NO synthase (NOS).The complex reaction involves the transfer of electrons from NADPH, via the flavins FAD and … 1993 Jul 30;194(2):654-8. doi: 10.1006/bbrc.1993.1871.

HDAC6 Mediates Macrophage iNOS Expression and Excessive Nitric Oxide Production in the Blood During Endotoxemia. Additionally, X-ray crystal and cryogenic electron microscopy structures have shed new insights on the structure and regulation of this enzyme. Gheibi S, Samsonov AP, Gheibi S, Vazquez AB, Kashfi K. Biochem Pharmacol. 1991 Mar;12(3):A17-21. In animals, nitric oxide (NO) is mainly produced by NO synthases (NOSes), a family of enzymes partly conserved in bacteria. A better understanding of iNOS' complex functions is necessary before specific drug candidates can be identified for classical indications such as sepsis, heart failure, and pain; however, newer promising indications for iNOS inhibition, such as depression, neurodegenerative disorders, and epilepsy, have been discovered. A considerable number of human diseases have an inflammatory component, and a key mediator of immune activation and inflammation is inducible nitric oxide synthase (iNOS), which produces nitric oxide … This review summarizes the structure, function, and regulation of iNOS, with focus on the development of iNOS inhibitors (historical and recent).

Overexpressed or dysregulated iNOS has been implicated in numerous pathologies including sepsis, cancer, neurodegeneration, and various types of pain. Epub 2020 Jul 7.  |  You can compare the structures of the bacterial enzymes with the mammalian enzymes using the "Structure Comparison" tool at the PDB. In the vascular system, when activated, arginase can compete with nitric oxide synthase (NOS) for their common substrate, L-arginine. 25. Once it was discovered that the enzyme nitric oxide synthase (NOS) is responsible for the biosynthesis of NO, NOS became a drug target. Nitric oxide synthases in neuronal cells, macrophages and endothelium are NADPH diaphorases, but represent only a fraction of total cellular NADPH diaphorase activity.
