So, this causes the G-protein to becomes permanently activated and it keeps activating a membrane-bound protein called adenylate cyclase.

因此，这导致G蛋白被永，并继续称为腺苷酸环化酶膜结合蛋白。

The nitric oxide diffuses into the nearby smooth muscle cells, and activates guanylate cyclase, which converts GTP molecules to cGMP.

一氧化氮扩散平滑肌细胞，鸟苷酸环化酶，将GTP分子转化为cGMP。

The G protein activates adenylate cyclase, the enzyme that catalyzes the production of cAMP from ATP.

G蛋白腺苷酸环化酶，该酶催化ATP生成cAMP。
