Protein attributes

Sequence length	602 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	First step of mRNA capping. Converts the 5'-triphosphate end of a nascent mRNA chain into a diphosphate end By similarity.
Catalytic activity	A 5'-phosphopolynucleotide + H2O = a polynucleotide + phosphate.
Cofactor	Divalent ions By similarity.
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 fungal TPase family.
