Reaction: Methylation of GMP-cap by RNA Methyltransferase
- in pathway: mRNA Capping
In the final step of the capping reaction, the methyltransferase takes a methyl group from S-adenosyl-methionine to the N7 position of the cap guanine. N7G-methyltransferase (MT) mediated reaction can be represented as:
GpppN(pN)n + S-adenosylmethionine (Adomet) ->m7GpppN(pN)n + S-adenosylhomocysteine (Adohcy).
GpppN(pN)n + S-adenosylmethionine (Adomet) ->m7GpppN(pN)n + S-adenosylhomocysteine (Adohcy).
