inactive form

Rapl, like Ras, cycles between a GDP bound inactive form and a GTP-bound active form.

Rap1,和Ras一样, 具有GDP结合的无活性形式和GTP结合的活性形式.

Once inside the tumor cell, the compounds convert from inactive form into an active anti-cancer drug.

一旦进入瘤细胞, 这些复合物便由非活性形态转化成活性抗肿瘤药物.

Normally MMPs exist as zymogen in the inactive form and their modulations are controlled at multi-levels. Their activations are mediated by serine protease or fibrinase. In addition, they can also be activated by autocatalysis and modulated by their specific tissue inhibitor of MMPs ( TIMPs).

通常情况下，MMPs受多层次的调控并以酶原的形式存在，激活过程受丝氨酸蛋白酶或纤维蛋白酶的介导，也可以自主催化激活，此外还受其特异性组织抑制剂（TIMPs）的调节。
