Arabidopsis	At5g50240	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.	A second protein L-isoaspartyl methyltransferase gene in Arabidopsis produces two transcripts whose products are sequestered in the nucleus.; 2004; DOI: 10.1104/pp.104.046094; PMID: 15347786; https://pubmed.ncbi.nlm.nih.gov/15347786/ | Arabidopsis Protein Repair L-Isoaspartyl Methyltransferases: Predominant Activities at Lethal Temperatures.; 2006; DOI: 10.1111/j.1399-3054.2006.00772.x; PMID: 21076691; https://pubmed.ncbi.nlm.nih.gov/21076691/
