Function

[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

Development of potent and isoform selective nitric oxide synthase (NOS) inhibitors is challenging because of the structural similarity in the heme active sites. One amino acid difference between NOS isoforms, Asp597 in rat neuronal NOS (nNOS) versus Asn368 in bovine endothelial NOS (eNOS), has been identified as the structural basis for why some dipeptide amide inhibitors bind more tightly to nNOS than to eNOS. We now have found that the same amino acid variation is responsible for substantially different binding modes and affinity for a new class of aminopyridine-based inhibitors.
