Structural highlights
Function[LCMT1_YEAST] 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.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe important role of the serine/threonine protein phosphatase 2A (PP2A) in various cellular processes requires a precise and dynamic regulation of PP2A activity, localization, and substrate specificity. The regulation of the function of PP2A involves the reversible methylation of the COOH group of the C-terminal leucine of the catalytic subunit, which, in turn, controls the enzyme's heteromultimeric composition and confers different protein recognition and substrate specificity. We have determined the structure of PPM1, the yeast methyltransferase responsible for methylation of PP2A. The structure of PPM1 reveals a common S-adenosyl-l-methionine-dependent methyltransferase fold, with several insertions conferring the specific function and substrate recognition. The complexes with the S-adenosyl-l-methionine methyl donor and the S-adenosyl-l-homocysteine product and inhibitor unambiguously revealed the co-substrate binding site and provided a convincing hypothesis for the PP2A C-terminal peptide binding site. The structure of PPM1 in a second crystal form provides clues to the dynamic nature of the PPM1/PP2A interaction.
