Comments [?]

case <OC:Bacillales>
Function Hydrolyzes pyrophosphate formed during P-Ser-HPr dephosphorylation by HPrK/P. Might play a role in controlling the intracellular pyrophosphate pool.
end case
Catalytic activity RHEA:24576: diphosphate + H2O = H(+) + 2 phosphate
EC 3.6.1.1
Cofactor Mg(2+)
Similarity Belongs to the HAD-like hydrolase superfamily. PpaX family.
