Phosphatase that is active on 2-deoxy-D-glucose 6-phosphate (2-DOG-6P), but not very active on fructose-1-P. 2-deoxy-D-glucose 6-phosphate + H2O = 2-deoxy-D-glucose + phosphate Optimum pH is 6. Optimum temperature is 40 degrees Celsius. Present with 2400 molecules/cell in log phase SD medium. Belongs to the HAD-like hydrolase superfamily. DOG/GPP family.
