PIMT1

Gene
PIMT1
Protein
Protein-L-isoaspartate O-methyltransferase 1
Organism
Arabidopsis thaliana
Length
230 amino acids
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. Contributes to seed longevity and germination vigor by limiting the abnormal accumulation of the L-isoaspartyl residues in seed proteins.
Similarity
Belongs to the methyltransferase superfamily. L-isoaspartyl/D-aspartyl protein methyltransferase family.
Mass
24.614 kDa
