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         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.
