Protein attributes

Sequence length	208 AA.
Sequence status	Complete.
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. HAMAP MF_00090
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 HAMAP MF_00090.
Sequence similarities	Belongs to the methyltransferase superfamily. L-isoaspartyl/D-aspartyl protein methyltransferase family.
