Cultivar variation in heat stability and kinetic properties of soluble invertase in wheat grains

Soluble invertase from mid-milky stage grains of two wheat variaties (Kalyansona and PBW 343) was isolated and purifield by employing ammonium sulphate precipitation, gel filtration and column chromatography. The two varieties showed differential response in respect to thermodynamic properties of th...

Summary:Soluble invertase from mid-milky stage grains of two wheat variaties (Kalyansona and PBW 343) was isolated and purifield by employing ammonium sulphate precipitation, gel filtration and column chromatography. The two varieties showed differential response in respect to thermodynamic properties of the enzyme. The results suggest that genetic differences exist in soluble invertase properties of wheat grains and the thermal adaptation of the enzyme is reflected in its altered kinetic behaviour
