Enzyme Information
| 2.7.7.50 | mRNA guanylyltransferase. based on mapping to UniProt P04298 GTP + (5')pp-Pur-mRNA = diphosphate + G(5')ppp-Pur-mRNA. -!- Can modify also synthetic poly(A) and poly(G) to form the structures m(7)G(5')pppAn and m(7)G(5')pppGn. | 
| 3.1.3.33 | Polynucleotide 5'-phosphatase. based on mapping to UniProt P04298 A 5'-phosphopolynucleotide + H(2)O = a polynucleotide + phosphate. -!- Does not act on nucleoside monophosphates. -!- Induced in Escherichia coli by T-even phages. | 
| 2.1.1.56 | mRNA (guanine-N(7)-)-methyltransferase. based on mapping to UniProt P04298 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. |
