General function:
Involved in hydrolase activity
Specific function:
May 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)
Gene Name:
Uniprot ID:
Molecular weight:
Diphospho-myo-inositol polyphosphate + H(2)O → myo-inositol polyphosphate + phosphate.
General function:
Involved in inositol trisphosphate 3-kinase activity
Specific function:
Converts inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7/PP-InsP5). Involved in phosphate regulation and polyphosphate accumulation. Required for resistance to salt stress, cell wall integrity, vacuole morphogenesis, and telomere maintenance
Gene Name:
Uniprot ID:
Molecular weight:
ATP + 1D-myo-inositol hexakisphosphate → ADP + 5-diphospho-1D-myo-inositol (1,2,3,4,6)pentakisphosphate.
ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate → ADP + diphospho-1D-myo-inositol tetrakisphosphate (isomeric configuration unknown).
General function:
Involved in acid phosphatase activity
Specific function:
Bifunctional inositol kinase that catalyzes the formation of diphosphoinositol pentakisphosphate (InsP7 or PP- InsP5) and bi-diphosphoinositol tetrakisphosphate (InsP8 or PP2- InsP4). Converts inositolitol hexakisphosphate (InsP6) to InsP7. Also able to convert InsP7 to InsP8. Probably specifically mediates the formation of 4PP-InsP5 and 6PP-InsP5 InsP7 isomers but not of 5PP-IP5 InsP7 isomer. Required for maintaining celllular integrity, normal growth and interactions with the ARP complex. Acts as a regulator of the PHO80-PHO85 cyclin/cyclin-dependent kinase (CDK) complex, thereby regulating signaling of phosphate availability. Required for the function of the cortical actin cytoskeleton, possibly by participating in correct F-actin localization and ensuring polarized growth
