Researchers discover new enzymes central to cell function

(Case Western Reserve University) Doctors have long treated heart attacks, improved asthma symptoms, and cured impotence by increasing levels of a single molecule in the body: nitric oxide. The tiny molecule can change how proteins function. But new research featured in Molecular Cell suggests supplementing nitric oxide--NO--is only the first step. Researchers have discovered previously unknown enzymes in the body that convert NO into 'stopgap' molecules--SNOs--that then modulate proteins. The newly discovered enzymes help NO have diverse roles in cells.
