A cDNA encoding a novel protein phosphatase catalytic subunit (protein phosphatase X) has been isolated from a rabbit liver library. It codes for a protein having 45% and 65% amino acid sequence identity, respectively, to the catalytic subunits of protein phosphatase 1 and protein phosphatase 2A from skeletal muscle. The enzyme is neither the hepatic form of protein phosphatase 1 or 2A, nor is it protein phosphatase 2B or 2C. The possible identity of protein phosphatase X is discussed.
一种编码新型蛋白磷酸酶催化亚基（蛋白磷酸酶X）的互补DNA（cDNA）已从兔肝文库中分离出来。它编码的蛋白质与骨骼肌中的蛋白磷酸酶1和蛋白磷酸酶2A的催化亚基的氨基酸序列分别具有45%和65%的同一性。该酶既不是蛋白磷酸酶1或2A的肝脏形式，也不是蛋白磷酸酶2B或2C。文中讨论了蛋白磷酸酶X可能的身份。
