Abstract
A lectin was isolated from Agrobacterium radiobacter cell surface and purified. It is a monomer of 40 kDa as shown by SDS-PAGE. The lectin has a pI of 9.15 and amino acid composition of the lectin shows that 44% of the amino acids are hydrophobic. The lectin agglutinates rabbit erythrocytes but does not agglutinate human erythrocytes. It does not show specificity for monosaccharides except for D-glucosamine. Fetuin and its N-linked glycopeptide also inhibit the activity of the lectin but greater inhibition is shown by locust bean gum and Nicotiana tobaccum (tobacco) tissue extracts.
