- General Function
- Protein-l-isoaspartate (d-aspartate) o-methyltransferase activity
- 年代pecific 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.
