CC -!- FUNCTION: Phosphatase with a broad specificity. Its primary
CC physiological function is to dephosphorylate 3'-phosphoadenosine 5'-
CC phosphate (PAP) and 3'-phosphoadenosine 5'-phosphosulfate (PAPS). Thus,
CC plays a role in mycobacterial sulfur metabolism, since it can serve as
CC a key regulator of the sulfate assimilation pathway by controlling the
CC pools of PAP and PAPS in the cell. To a lesser extent, is also able to
CC hydrolyze inositol 1-phosphate (I-1-P), fructose 1,6-bisphosphate (FBP)
CC (to fructose 6-phosphate (F-6-P)) and AMP in vitro, but this might not
CC be significant in vivo (By similarity). {ECO:0000250}.

CC phosphate + phosphate; Xref=Rhea:RHEA:11064, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:32966, ChEBI:CHEBI:43474, ChEBI:CHEBI:57634; EC=3.1.3.11;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a myo-inositol phosphate + H2O = myo-inositol + phosphate;
CC Xref=Rhea:RHEA:24056, ChEBI:CHEBI:15377, ChEBI:CHEBI:17268,
