Protein

Leucine carboxyl methyltransferase 1

Gene

PPM1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Methylates the carboxyl group of the C-terminal leucine residue of protein phosphatase 2A catalytic subunits to form alpha-leucine ester residues. Acts on the two major protein phosphatase 2A catalytic subunits, PPH21 and PPH22.2 Publications

Catalytic activityi

S-adenosyl-L-methionine + [phosphatase 2A protein]-leucine = S-adenosyl-L-homocysteine + [phosphatase 2A protein]-leucine methyl ester.

Enzyme regulationi

Inhibited by S-adenosyl-L-homocysteine.
