Comments

FUNCTION: Catalyzes the first two reactions in the mRNA cap formation pathway.
CATALYTIC ACTIVITY: A 5'-phosphopolynucleotide + H₂O = a polynucleotide + phosphate.
CATALYTIC ACTIVITY: GTP + (5')pp-Pur-mRNA = diphosphate + G(5')ppp-Pur-mRNA.
SUBUNIT: Heterodimer of a large and a small subunit (By similarity).
SIMILARITY: Belongs to the viral GTase family.
