Protein attributes

Sequence length	476 AA.
Sequence status	Complete.
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.
