Newly mapped enzyme could yield new treatments for female sexual dysfunction

itual. At one critical step in that pathway, nitric oxide synthase converts arginine, one of the 20 natural amino acids, into citrulline and nitric oxide. The latter product causes rapid relaxation of smooth muscle in male and female genitalia, allowing the thousands of tiny vessels there to swell with blood.

Arginase can derail this reaction by sequestering arginine and breaking it down into compounds unrelated to those physiologically responsible for arousal, depriving the genitalia of the nitric oxide needed for sexual function.

In both men and women, sexual dysfunction occurs when this enzyme-mediated pathway goes awry, impeding blood flow in and out of the genitalia. Sexual difficulty often manifests itself as a side effect of heart disease, hypertension, diabetes and the use of medications such as antidepressants.
