Nitric oxide synthase type I (nNOS)

Target
nNOS
Molecular classification
Enzyme
01

Overview

Nitric oxide synthase type I/nNOS catalyzes NO production from L‑arginine using multiple cofactors through a dimeric structure requiring calcium/calmodulin for activation. It plays essential roles primarily within neural tissues but impacts broader physiological processes including blood flow regulation and immune modulation. Dysfunctional nNOS activity contributes to several disease states via altered NO signaling pathways.
