Cloned (Comment) Organism
expression of the enzyme in three inducible yeast systems: Saccharomyces cerevisiae (pYES2), Schizosaccharomyces pombe (pDS472a), and Pichia pastoris (pPICZalphaA), and one constitutive system: Pichia pastoris (pGAPTalphaA). During 8-day batch fermentation in shaking flasks, the inducible Pichia system produces the highest activity whereas the Schizosaccharomyces pombe system produces the lowest activity. The enzyme may be a 3-phytase, EC 3.1.3.8, or a 6-phytase, EC 3.1.3.26. The product of the hydrolysis of myo-inositol hexakisphosphate i.e. myo-inositol 1,2,3,4,5-pentakisphosphate or myo-inositol 1,3,4,5,6-pentakisphosphate has not been identified Escherichia coli
