磷酸酶

半胱氨酸依赖的磷酸酶催化酪氨酸去磷酸化的机制。

磷酸酶是一种能够将对应底物去磷酸化的酶,即通过水解磷酸单酯将底物分子上的磷酸基团除去,并生成磷酸根离子和自由的羟基。磷酸酶的作用与激酶的作用正相反,激酶是磷酸化酶,可以利用能量分子,如ATP,将磷酸基团加到对应底物分子上。在许多生物体中都普遍存在的一种磷酸酶是碱性磷酸酶。

磷酸酶可以被分为两类:半胱氨酸依赖的磷酸酶和金属磷酸酶(其活性依赖位于活性位点上的金属离子)。

英语百科

Phosphatase 磷酸酶

A phosphatase is an enzyme that removes a phosphate group from its substrate by hydrolysing phosphoric acid monoesters into a phosphate ion and a molecule with a free hydroxyl group (see dephosphorylation). This action is directly opposite to that of phosphorylases and kinases, which attach phosphate groups to their substrates by using energetic molecules like ATP. A common phosphatase in many organisms is alkaline phosphatase. Another large group of proteins present in archaea, bacteria, and eukaryote exhibits deoxyribonucleotide and ribonucleotide phosphatase or pyrophosphatase activities that catalyse the decomposition of dNTP/NTP into dNDP/NDP and a free phosphate ion or dNMP/NMP and a free pyrophosphate ion. The other group of phosphatase is collectively called as protein phosphatase, which removes a phosphate group from the phosphorylated amino acid residue of the substrate protein. Protein phosphorylation is a common posttranslational modification of protein catalyzed by protein kinases, and protein phosphatases reverse the effect.
