A. is linked with angina.
B. like adenylyl cyclase, converts NTPs to CNTPs.
C. causes a cGMP cascade that activates protein kinase C.
D. and adenylyl cyclase can bind extracellular signal molecules.
Guanylyl cyclase is involved in the signal transduction in plants. Phytochrome activation leads to an increase in cytosolic Ca2+ levels. Aside from this, phytochrome also undergoes a change in shape. This leads to the subsequent activation of guanylyl cyclase.
