Diversified Carbohydrate-Binding Lectins from Marine Resources
Marine bioresources produce a great variety of specific and potent bioactive molecules including natural organic compounds such as fatty acids, polysaccharides, polyether, peptides, proteins, and enzymes. Lectins are also one of the promising candidates for useful therapeutic agents because they can recognize the specific carbohydrate structures such as proteoglycans, glycoproteins, and glycoli...
متن کاملLectins as Carbohydrate-binding Proteins
Lectins are cell-binding and agglutinating (glyco)proteins found in a variety of living forms. They will be defined here as homogeneous carbohydrate-binding (glyco)proteins principally of plant (seed) origin but also occurring in invertebrate (and vertebrate?) forms. In recent years, lectins have been employed in studying a wide range of biological phenomena including cell differentiation and m...
متن کاملCarbohydrate binding activities of Bradyrhizobium japonicum. II. Isolation and characterization of a galactose-specific lectin
Extracts of Bradyrhizobium japonicum were fractionated on Sepharose columns covalently derivatized with lactose. Elution of the material that was specifically bound to the affinity column with lactose yielded a protein of Mr approximately 38,000. Isoelectric focusing of this sample yielded two spots with pI values of 6.4 and 6.8. This protein specifically bound to galactose-containing glycoconj...

The morphology of 11 species of the genus Vicia from Iran was studied using Scanning Electron Microscopy (SEM). The main pattern in seed coat sculpturing in the species was papillose, but the size and the number of side ribs in papillae and the density of papillae, were different in various species. Four morphological characters of seeds: relative hilum length and shape, relative position of th...
