guanylate cyclase

Guanylate cyclase is an enzyme that plays a crucial role in cellular signaling. It converts a molecule called GTP into another molecule called cyclic GMP (cGMP). This process is important because cGMP acts as a cellular messenger, helping transmit signals within cells. These signals can affect various physiological processes, such as blood vessel dilation, regulating blood pressure, and influencing nerve signal transmission. Guanylate cyclase can be activated by nitric oxide, which is released during certain biological processes, making it essential in areas like cardiovascular health and the function of the nervous system.
