Protein attributes

Sequence length	208 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the methyl esterification of L-isoaspartyl residues in peptides and proteins that result from spontaneous decomposition of normal L-aspartyl and L-asparaginyl residues. It plays a role in the repair and/or degradation of damaged proteins By similarity.
Catalytic activity	S-adenosyl-L-methionine + protein L-isoaspartate = S-adenosyl-L-homocysteine + protein L-isoaspartate alpha-methyl ester. HAMAP MF_00090
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the L-isoaspartyl/D-aspartyl protein methyltransferase family.
