Lectins are carbohydrate-binding proteins of non-immune origin that agglutinate cells or precipitate glycoconjugates.Based on evolutionary and structural relatedness, seven lectin families have been distinguished, of which legume lectins are the best characterized. Lectins typically constitute a large fraction of the total protein in most leguminous seeds and plant storage tissues where they play an important role in several defense mechanisms. A lectin from the seeds of Indigofera heterantha, member of family leguminosae was isolated, purified, partially characterized and its antimicrobial...

Lectins are proteins or glycoproteins of non immune origin which have a wide distribution in animals, plants, and microorganisms. Their medicinal role extends from simple antimicrobial action to anti- tumour properties.In view of the advancement in understanding the potential medicinal role of the plant lectins, a lectin from the leaves of Prunella vulgaris was isolated, purified, partially characterized and its antimicrobial activity evaluated. The lectin is specific for galactose and N-acetyl-galactosamine The molecular weight of the lectin as determined by SDS-PAGE was 32500 Da and that...
