Lima bean LBA is isolated from Lima bean seeds and purified by affinity chromatography. LBA consists of 30,000 Da subunits, two of which are connected by disulfide bonds. Each subunit contains a cysteine residue, which is necessary for its carbohydrate and metal ion binding activity. It has the carbohydrate specificity of terminal GalNAc (1,3)Gal and is eluted with n-acetylgalactosamine. LBA agglutinated type A erythrocytes.
