Isolation of a lectin from apple pollen. Lectins are present in plants (and animals), they are proteins that that bind to carboh

So a study on biochemical, physiological and molecular levels is required to explore the importance of Lectin in the plant cell. Lectin is present in many forms in the plant cells. The pollen grains of the apple are found to have some group of Lectin. These Lectin are heterodimers and have a great affinity for the glycopeptides with a molecular weight of 30,000 Daltons and have two subunits with N-acetyl glucosamine residues. Arabinose is found linked to the polypeptide chain as ?-L-arabinofuranosides through the hydroxylproline residues. (Sharon and Lis, 2007). The glycopeptides are found to contain lesser amount of serine, S-carboxyl methyl cysteine and other amino acids such as glycine as major amino acids. Cysteine (16%), Hydroxyproline (11%) and Glycine (12%) is the major amino acid composition of lectin. Lectin agglutinates the cells and precipitates the complex carbohydrates. The lectin has Arabinose monosachharide (93%) and Galactose (7.5%) of the total 37% carbohydrate content of lectin. (Sharon and Lis, 2007). ...

Summary

Isolation of a Lectin from apple pollen Introduction: Lectins are glycoprotein present in the plants and animals. These Lectins are found in seeds, barks, fungi, plant roots, sea weeds and sponges, mollusks, fish eggs and body fluids of invertebrates. Lectin is involved in the processes such as transport of carbohydrates, cell wall elongation, cell-cell interaction, membrane receptor recognizers, storage proteins, growth regulation, self incompatibility and also functions as enzymes…
