nitric oxide synthase

[‚nī·trik ¦äk‚sīd ¦sin‚thās]
(biochemistry)
An enzyme that catalyzes the stepwise conversion of the amino acid L-arginine to nitric oxide and L-citrulline. There are three types: the brain (or neuronal) and epithelial nitric oxide synthases, which are always present in cells, and inducible nitric oxide synthase, which is produced as needed.
