CC   -!- FUNCTION: Hydrolyzes pyrophosphate formed during P-Ser-HPr
CC       dephosphorylation by HPrK/P. Might play a role in controlling the
CC       intracellular pyrophosphate pool. {ECO:0000255|HAMAP-Rule:MF_01250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=diphosphate + H2O = H(+) + 2 phosphate; Xref=Rhea:RHEA:24576,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:43474; EC=3.6.1.1; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01250};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01250};
CC   -!- SIMILARITY: Belongs to the HAD-like hydrolase superfamily. PpaX family.
CC       {ECO:0000255|HAMAP-Rule:MF_01250}.
