Metal-dependent phosphatase that shows phosphatase activity against several substrates, including fructose-1-phosphate and fructose-6-phosphate (By similarity). Its preference for fructose-1-phosphate, a strong glycating agent that causes DNA damage rather than a canonical yeast metabolite, suggests a damage-control function in hexose phosphate metabolism (By similarity). beta-D-fructose 1-phosphate + H2O = D-fructose + phosphate beta-D-fructose 6-phosphate = D-glyceraldehyde 3-phosphate + dihydroxyacetone Subfamily III proteins have a conserved RTxK motif about 40-50 residues from the C-terminus; the threonine may be replaced by serine or cysteine. Belongs to the damage-control phosphatase family. Sugar phosphate phosphatase III subfamily.
