CC -!- FUNCTION: Cleaves A-5'-PPP-5'A to yield AMP and ADP. Can cleave all
CC dinucleoside polyphosphates, provided the phosphate chain contains at
CC least 3 phosphates and that 1 of the 2 bases composing the nucleotide
CC is a purine. Is most effective on dinucleoside triphosphates.
CC Negatively regulates intracellular dinucleoside polyphosphate levels,
CC which elevate following heat shock. {ECO:0000269|PubMed:12028594,
CC ECO:0000269|PubMed:9573184}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + P(1),P(3)-bis(5'-adenosyl) triphosphate = ADP + AMP + 2
CC H(+); Xref=Rhea:RHEA:13893, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Note=Divalent metal cations. Mn(2+) is the preferred ion.;
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=5.3 uM for P(1)-P(3)-bis(5'-adenosyl) triphosphate
