>TIGR00080 pimt protein-L-isoaspartate O-methyltransferase; InterPro: IPR000682 Protein-L-isoaspartate(D-aspartate) O-methyltransferase () (PCMT) (which is also known as L-isoaspartyl protein carboxyl methyltransferase) is an enzyme that catalyzes the transfer of a methyl group from S- adenosylmethionine to the free carboxyl groups of D-aspartyl or L-isoaspartyl residues in a variety of peptides and proteins. The enzyme does not act on normal L-aspartyl residues L-isoaspartyl and D-aspartyl are the products of the spontaneous deamidation and/or isomerization of normal L-aspartyl and L- asparaginyl residues in proteins. PCMT plays a role in the repair and/or degradation of these damaged proteins; the enzymatic methyl esterification of the abnormal residues can lead to their conversion to normal L-aspartyl residues. The SAM domain is present in most of these proteins.; GO: 0004719 protein-L-isoaspartate (D-aspartate) O-methyltransferase activity, 0006464 protein modification process.
