Protein attributes

Sequence length	391 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Second step of mRNA capping. Transfer of the GMP moiety of GTP to the 5'-end of RNA via an enzyme-GMP covalent reaction intermediate By similarity.
Catalytic activity	GTP + (5')pp-Pur-mRNA = diphosphate + G(5')ppp-Pur-mRNA.
Subunit structure	The mRNA-capping enzyme is composed of two separate chains alpha and beta, respectively a mRNA guanylyltransferase and an RNA 5'-triphosphatase By similarity.
Subcellular location	Nucleus By similarity.
Sequence similarities	Belongs to the eukaryotic GTase family.
