Abstract

A galactose-specific lectin was isolated from the seeds of Erythrina edulis. The protein was purified by affinity chromatography of the globulin fraction on an allyl-galactoside polyacrylamide gel. The hemagglutination properties, amino acid composition, A 280, MW of the protein and of its subunits, carbohydrate content, electrophoretic pattern and isoelectric point were determined. Comparison of its properties with those of other Erythrina lectins shows that the protein is a distinct member of this group of lectins.
