mRNA guanylyltransferase
Class of enzymes
In enzymology, a mRNA guanylyltransferase (EC 2.7.7.50) is an enzyme that catalyzes the chemical reaction
- GTP + (5')ppPur-mRNA diphosphate + G(5')pppPur-mRNA
Thus, the two substrates of this enzyme are GTP and (5')ppPur-mRNA, whereas its two products are diphosphate and G(5')pppPur-mRNA.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).op The systematic name of this enzyme class is GTP:mRNA guanylyltransferase. Other names in common use include mRNA capping enzyme, messenger RNA guanylyltransferase, and Protein 2.
