CC -!- FUNCTION: Catalyzes the methyl esterification of L-isoaspartyl residues
CC in peptides and proteins that result from spontaneous decomposition of
CC normal L-aspartyl and L-asparaginyl residues. It plays a role in the
CC repair and/or degradation of damaged proteins. {ECO:0000255|HAMAP-
CC Rule:MF_00090}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[protein]-L-isoaspartate + S-adenosyl-L-methionine =
CC [protein]-L-isoaspartate alpha-methyl ester + S-adenosyl-L-
CC homocysteine; Xref=Rhea:RHEA:12705, Rhea:RHEA-COMP:12143, Rhea:RHEA-
CC COMP:12144, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:90596,
CC ChEBI:CHEBI:90598; EC=2.1.1.77; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00090};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00090}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. L-
CC isoaspartyl/D-aspartyl protein methyltransferase family.
CC {ECO:0000255|HAMAP-Rule:MF_00090}.
