Enzyme Information

2.1.1.56
mRNA (guanine-N(7)-)-methyltransferase.
based on mapping to UniProt Q8SR66
S-adenosyl-L-methionine + G(5')pppR-RNA = S-adenosyl-L-homocysteine + m(7)G(5')pppR-RNA.
-!- Adds an N(7)-methylguanine cap to mRNA. -!- The nucleoside next to the terminal guanosine may be either guanosine or adenosine.
