Abstract:
Some characteristics of polygalacturonase inhibiting protein (PGIP) in wheat are reported in this paper.The PGIP is a glycoprotein and contains 6.89% of carbohydrates. It is instable in heat. Its isoelectric points are PH 9.1 and 9.4 on the isoelectric focusing. The optimum PGIP activity is at PH 1.0~5.5. The amino acid composition of PGIP subunit.effect of PH,ionic strength and temperature on PGIP were determined.
