Accepted name: [phosphatase 2A protein]-leucine-carboxy methyltransferase
Reaction: S-adenosyl-L-methionine + [phosphatase 2A protein]-leucine = S-adenosyl-L-homocysteine + [phosphatase 2A protein]-leucine methyl ester
Other name(s): leucine carboxy methyltransferase-1; LCMT1
Systematic name: S-adenosyl-L-methionine:[phosphatase 2A protein]-leucine O-methyltransferase
Comments: Methylates the C-terminal leucine of phosphatase 2A. A key regulator of protein phosphatase 2A. The methyl ester is hydrolysed by EC (protein phosphatase methylesterase-1). Occurs mainly in the cytoplasm, Golgi region and late endosomes.
