Identification
NameDiphosphoinositol polyphosphate phosphohydrolase DDP1
Synonyms
  • Diadenosine 5',5'''-P1,P6-hexaphosphate hydrolase
  • AP6A hydrolase
  • Diadenosine and diphosphoinositol polyphosphate phosphohydrolase 1
Gene NameDDP1
Enzyme Class
Biological Properties
General FunctionInvolved in hydrolase activity
Specific FunctionMay eliminate potentially toxic dinucleoside polyphosphates during sporulation. Most active against diadenosine 5',5'''-P1,P6-hexaphosphate (Ap6A). Can also hydrolyze diadenosine 5',5'''-P1,P5-pentaphosphate (Ap5A), adenosine 5'-pentaphosphate, and adenosine 5'-tetraphosphate are also substrates, but not diadenosine 5',5'''-P1,P4-tetraphosphate (Ap4A) or other dinucleotides, mononucleotides, nucleotide sugars, or nucleotide alcohols. Also cleaves a beta-phosphate from the diphosphate groups in PP-InsP5 (diphosphoinositol pentakisphosphate) and [PP]2-InsP4 (bisdiphosphoinositol tetrakisphosphate)
