N-methyltransferase that catalyzes the formation of anserine (beta-alanyl-N(Pi)-methyl-L-histidine) from carnosine. Anserine, a methylated derivative of carnosine (beta-alanyl-L-histidine), is an abundant constituent of vertebrate skeletal muscles. Also methylates other L-histidine-containing di- and tripeptides such as Gly-Gly-His, Gly-His and homocarnosine (GABA-His). Source: Recombinant protein corresponding to aa50-400 from mouse Carnosine N-methyltransferase, fused to 6X His-SUMO-Tag at N-terminal, expressed in E.coli.
