The tyrosine and dual-specificity phosphatases are involved in signaling, cell growth and differentiation, and the cell cycle. The enzymes share a common catalytic mechanism mediated by an active site cysteine, arginine and aspartic acid. Supplementary domains assist in targeting and substrate specificity.
酪氨酸磷酸酶和双特异性磷酸酶参与信号传导、细胞生长与分化以及细胞周期。这些酶具有由活性位点半胱氨酸、精氨酸和天冬氨酸介导的共同催化机制。辅助结构域有助于靶向作用和底物特异性。
