==MURINE INDUCIBLE NITRIC OXIDE SYNTHASE OXYGENASE DOMAIN (DELTA 114), AMINOGUANIDINE COMPLEX==
-
The nitric oxide synthase oxygenase domain (NOSox) oxidizes arginine to, synthesize the cellular signal and defensive cytotoxin nitric oxide (NO)., Crystal structures determined for cytokine-inducible NOSox reveal an, unusual fold and heme environment for stabilization of activated oxygen, intermediates key for catalysis. A winged beta sheet engenders a curved, alpha-beta domain resembling a baseball catcher's mitt with heme clasped, in the palm. The location of exposed hydrophobic residues and the results, of mutational analysis place the dimer interface adjacent to the, heme-binding pocket. Juxtaposed hydrophobic O2- and polar, L-arginine-binding sites occupied by imidazole and aminoguanidine, respectively, provide a template for designing dual-function inhibitors, and imply substrate-assisted catalysis.

== Function ==
 +
[https://www.uniprot.org/uniprot/NOS2_MOUSE NOS2_MOUSE] Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In macrophages, NO mediates tumoricidal and bactericidal actions. Also has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such COX2.<ref>PMID:16373578</ref>
