| + | [https://www.uniprot.org/uniprot/CYSQ_MYCTU CYSQ_MYCTU] Phosphatase with a broad specificity. Its primary physiological function is to dephosphorylate 3'-phosphoadenosine 5'-phosphate (PAP) and 3'-phosphoadenosine 5'-phosphosulfate (PAPS). Thus, plays a role in mycobacterial sulfur metabolism, since it can serve as a key regulator of the sulfate assimilation pathway by controlling the pools of PAP and PAPS in the cell. To a lesser extent, is also able to hydrolyze inositol 1-phosphate (I-1-P), fructose 1,6-bisphosphate (FBP) (to fructose 6-phosphate (F-6-P)) and AMP in vitro, but this might not be significant in vivo. Glucose-1-phosphate (G-1-P), p-nitrophenyl phosphate (pNPP), and beta-glycerol phosphate (beta-GP) are also good substrates, compared to I-1-P. With much lower efficiency, can also hydrolyze inositol 2-phosphate (I-2-P) and glucose-6-phosphate (G-6-P) in vitro, but not fructose-6-phosphate (F-6-P) and trehalose-6-phosphate (T-6-P).<ref>PMID:16325768</ref> <ref>PMID:18454554</ref> | ||
