cyklázy
Cyklázy are enzymes that catalyze the formation of cyclic molecules. In biochemistry, the most prominent examples are adenylyl cyclase and guanylyl cyclase. These enzymes play crucial roles in signal transduction pathways within cells.
Adenylyl cyclase, often referred to as AC, catalyzes the conversion of adenosine triphosphate (ATP) into cyclic
Guanylyl cyclase, or GC, catalyzes the conversion of guanosine triphosphate (GTP) into cyclic guanosine monophosphate (cGMP)
The activity of cyklázy is tightly regulated. Adenylyl cyclase can be activated or inhibited by G proteins,
