Superfamily Vaccinia Virus protein VP39
Functional Family Protein-L-isoaspartate O-methyltransferase

Enzyme Information

2.1.1.77
Protein-L-isoaspartate(D-aspartate) O-methyltransferase.
based on mapping to UniProt Q8TZR3
S-adenosyl-L-methionine + protein L-isoaspartate = S-adenosyl-L- homocysteine + protein L-isoaspartate alpha-methyl ester.
-!- D-aspartate (but not L-aspartate) residues in proteins can also act as acceptors. -!- Formerly EC 2.1.1.24.
