CC -!- POLYMORPHISM: The allele frequencies for the polymorphism at codon 120
CC differ between ethnic groups; in the Caucasian population Ile-120 is
CC present at a frequency of 0.45, while it is found at a frequency of
CC 0.88 and 0.81 in the Asian and the African populations respectively.
CC Val-120 is found at a frequency of 0.55 in the Caucasians, 0.12 and
CC 0.19 in the Asian and African populations respectively. The Ile-120
CC variant has higher specific activity and thermostability than the Val-
CC 120 variant. The Val-120 variant has a higher affinity for protein
CC substrates.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. L-
CC isoaspartyl/D-aspartyl protein methyltransferase family. {ECO:0000305}.
