SYSTEMATIC NAME
IUBMB Comments
5'-(N7-methyl 5'-triphosphoguanosine)-[mRNA] N7-methylguanosine 5'-phosphate phosphohydrolase
The enzyme removes (decaps) the N7-methylguanosine 5-phosphate cap from an mRNA degraded to a maximal length of 10 nucleotides [3,6]. Decapping is an important process in the control of eukaryotic mRNA degradation. The enzyme functions to clear the cell of cap structure following decay of the RNA body [2]. The nematode enzyme can also decap triply methylated substrates, 5'-(N2,N2,N7-trimethyl 5'-triphosphoguanosine)-[mRNA] [4].
