General annotation (Comments)

Function	May play a role in formation of virus factories and virus morphogenesis that occurs at the host endoplasmic reticulum membranes. Down-regulation of the level of PP-InsP5 (diphosphoinositol pentakisphosphate) may play a role in viral manipulation of the cellular secretory pathway, a step necessary for the formation of virions.
Catalytic activity	Diphospho-myo-inositol polyphosphate + H2O = myo-inositol polyphosphate + phosphate.
Cofactor	Magnesium or manganese.
Subcellular location	Host rough endoplasmic reticulum.
Sequence similarities	Belongs to the Nudix hydrolase family. DIPP subfamily. Contains 1 nudix hydrolase domain.
Biophysicochemical properties	Kinetic parameters: KM=1.2 µM for diphosphoinositol pentakisphosphate KM=0.67 mM for GTP KM=0.58 mM for p5A KM=0.92 mM for ATP KM=1.36 mM for p4A KM=1.70 mM for Gp4G KM=3.90 mM for Ap4A pH dependence: Optimum pH is 9.5.
