Protein: Polyol phosphate phosphatase PYP1 (EC 3.1.3.50) (P53981)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Hydrolyzes sugar alcohol (polyol) phosphates. Dephosphorylates a variety of substrates, including: sn-glycerol 1-phosphate (D-glycerol 3-phosphate), D-ribitol 5-phosphate, D-sorbitol 6-phosphate (D-glucitol 6-phosphate), and D-erythrose 4-phosphate. Prevents accumulation of toxic levels of polyol phosphates, which can impair glycolysis by inhibiting glucose-6-phosphate isomerase.
