Which enzyme is responsible for converting GTP to cGMP?

Explanation:
The enzyme responsible for converting GTP to cGMP is guanylate cyclase. Guanylate cyclase catalyzes the conversion of guanosine triphosphate (GTP) into cyclic guanosine monophosphate (cGMP), which acts as a secondary messenger in various signaling pathways within the cell. This process is significant in regulating various physiological functions, including vasodilation and neurotransmission. cGMP serves as a crucial signaling molecule that can activate protein kinases and influence numerous cellular actions. In contrast, adenylate cyclase primarily converts ATP to cyclic adenosine monophosphate (cAMP), phospholipase C is involved in the production of inositol trisphosphate and diacylglycerol from phosphatidylinositol 4,5-bisphosphate, and protein kinase G is a downstream effector activated by cGMP rather than an enzyme that converts GTP to cGMP. Thus, guanylate cyclase is the specific enzyme that fulfills the role of producing cGMP from GTP.
