ID   2.1.1.57
DE   methyltransferase cap1.
AN   cap1-MTase.
AN   messenger RNA (nucleoside-2'-)-methyltransferase.
AN   mRNA (nucleoside-2'-O)-methyltransferase.
CA   a 5'-end (N(7)-methyl 5'-triphosphoguanosine)-ribonucleoside in mRNA +
CA   S-adenosyl-L-methionine = a 5'-end (N(7)-methyl 5'-triphosphoguanosine)-
CA   (2'-O-methyl-ribonucleoside) in mRNA + H(+) + S-adenosyl-L-homocysteine.
CC   -!- This enzyme catalyzes the methylation of the ribose on the first
CC       transcribed nucleotide of mRNA or snRNA molecules.
CC   -!- This methylation event is known as cap1, and occurs in all mRNAs and
CC       snRNAs of higher eukaryotes, including insects, vertebrates and their
CC       viruses.
CC   -!- The human enzyme can also methylate mRNA molecules that lack
CC       methylation on the capping 5'-triphosphoguanosine.
CC   -!- Formerly EC 2.1.1.58.
