General Information
Term RNA cap trimethylguanosine synthase activity ID (Ontology) GO:0071164 (Gene Ontology)
Definition Catalysis of two successive methyl transfer reactions from AdoMet to the N-2 atom of guanosine, thereby converting 7-methylguanosine in an RNA cap to 2,2,7 trimethylguanosine.[ PubMed:11983179 PubMed:18775984 ]
Also Known As "cap hypermethylase activity" ; "RNA trimethylguanosine synthase activity"
