Function
Phosphatase with broad specificity; it can dephosphorylate fructose 1,6-bisphosphate, both D and L isomers of inositol-1-phosphate (I-1-P) but displaying a 20-fold higher rate of hydrolysis of D-I-1-P than of the L isomer, 2'-AMP, pNPP, inositol-2-phosphate, beta-glycerol phosphate, and alpha-D-glucose-1-phosphate. Cannot hydrolyze glucose-6-phosphate, fructose-6-phosphate, 5'-AMP and NAD(+). May be involved in the biosynthesis of a unique osmolyte, di-myo-inositol 1,1-phosphate.
