[Some properties of cotton plant phytase]

Some properties of phytase from cotton plant seeds were studied. The phytase activity was shown to increase during seed germination. The enzyme from cotton sprouts is not activated by Ca2+, Mg2+ and K+ and has the pH optimum of 5,0 and temperature optimum of 50 degrees. The molecular weight of the enzyme as determined by gel-filtration is 36000.
