Enzyme reactions

• Enzyme class: Chain A: E.C.2.1.1.57 - methyltransferase cap1.
• Reaction: a 5'-end (N(7)-methyl 5'-triphosphoguanosine)-ribonucleoside in mRNA + S-adenosyl-L-methionine = a 5'-end (N(7)-methyl 5'-triphosphoguanosine)- (2'-O-methyl-ribonucleoside) in mRNA + S-adenosyl-L-homocysteine + H⁺

5'-end (N(7)-methyl 5'-triphosphoguanosine)-ribonucleoside in mRNA + S-adenosyl-L-methionine = 5'-end (N(7)-methyl 5'-triphosphoguanosine)- (2'-O-methyl-ribonucleoside) in mRNA + S-adenosyl-L-homocysteine + H(+) (Bound ligand (Het Group name = TO1) matches with 56.67% similarity)
