Protein phosphatase methylesterase-1
Protein phosphatase methylesterase-1 (EC 3.1.1.89, PME-1, PPME1) is an enzyme with systematic name (phosphatase 2A protein)-leucine ester acylhydrolase.[1][2] This enzyme catalyses the following chemical reaction
- [phosphatase 2A protein]-leucine methyl ester + H2O [phosphatase 2A protein]-leucine + methanol
