synthase

 [sin´thās]
any enzyme, especially a lyase, which catalyzes a synthesis that does not involve the breakdown of a pyrophosphate bond, as opposed to ligase.

syn·thase

(sin'thās),
Trivial name used in the Enzyme Commission Report for a lyase reaction going in the reverse direction (NTP-independent). For individual synthases, see the specific names.

synthase

/syn·thase/ (-thās) a term used in the names of some enzymes, particularly lyases, when the synthetic aspect of the reaction is dominant or emphasized.

The role of endothelial nitric oxide synthase (eNOS) in normal physiology suggests that it could be a potential candidate gene for cardiovascular diseases.
Nitric oxide, synthesized in vascular endothelial cells from the abundant amino acid L-arginine by the enzyme endothelial nitric oxide synthase (eNOS), is a potent vasodilator.
As the first step in analyzing the complex biochemical choreography behind a floral scent, Pichersky and his coworkers in 1994 worked out the amino acid sequence of the enzyme linalool synthase from petals of Clarkia breweri, a purple wildflower native to California.
Now, the most interesting challenge is putting it together," says Raguso, who was a graduate student in Pichersky's lab in the early 1990s and whose work led to the discovery of the linalool synthase gene.
