[[http://www.uniprot.org/uniprot/NOS1_RAT NOS1_RAT]] Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In the brain and peripheral nervous system, NO displays many properties of a neurotransmitter. Inhibitory transmitter for non-adrenergic and non-cholinergic nerves in the colorectum. Probably has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such SRR. Inhibitory transmitter for non-adrenergic and non-cholinergic nerves in the colorectum.

== Publication Abstract from PubMed ==
 +
Nitric oxide synthases (NOSs) comprise three closely related isoforms that catalyze the oxidation of l-arginine to l-citrulline and the important second messenger nitric oxide (NO). Pharmacological selective inhibition of neuronal NOS (nNOS) has the potential to be therapeutically beneficial in various neurodegenerative diseases. Here, we present a structure-guided, selective nNOS inhibitor design based on the crystal structure of lead compound 1 in nNOS. The best inhibitor, 7, exhibited low nanomolar inhibitory potency and good isoform selectivities (nNOS over eNOS and iNOS are 472-fold and 239-fold, respectively). Consistent with the good selectivity, 7 binds to nNOS and eNOS with different binding modes. The distinctly different binding modes of 7, driven by the critical residue Asp597 in nNOS, offers compelling insight to explain its isozyme selectivity, which should guide future drug design programs.
