General rule information [?]

Accession PRU00924
Dates 25-NOV-2011 (Created)

Data class Domain
Predictors PROSITE; PS51591; RNA_CAP01_NS5_MT
Name mRNA cap 0 and cap 1 methyltransferase (EC 2.1.1.56 and EC 2.1.1.57)
Function mRNA (guanine-N(7)-)-methyltransferase (EC 2.1.1.56) is an enzyme that transfers a methyl group from SAM to G(5')pppR-RNA to form m(7)G(5')pppR-RNA and SAH. mRNA (nucleoside-2'-O-)-methyltransferase (EC 2.1.1.57) is an enzyme that transfers a methyl group from SAM to m(7)G(5')pppR-RNA to form m(7)G(5')pppRm-RNA and SAH.
