NOS Inhibitors

Santa Cruz Biotechnology now offers a broad range of NOS Inhibitors. Nitric oxide (NO) has a broad range of biological activities including cell signaling pathways in phylogenetically diverse species. Nitric oxide synthases (NOSs), the enzymes responsible for synthesis of NO, contain an N-terminal oxygenase domain and a C-terminal reductase domain. NOS activity requires homodimerization as well as three cosubstrates (L-arginine, NADPH and O2) and five cofactors or prosthetic groups (FAD, FMN, calmodulin, tetrahydrobiopterin and heme). NOS Inhibitors offered by Santa Cruz inhibit NOS and, in some cases, other cell signaling and nitric oxide synthesis related proteins. View detailed NOS Inhibitor specifications, including NOS Inhibitor CAS number, molecular weight, molecular formula and chemical structure, by clicking on the product name.
