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 کاملCarbohydrate specificity of lectins from Boletopsis leucomelas and Aralia cordate.
The carbohydrate specificity of three novel lectins, Boletopsis leucomelas lectin (BLL), Aralia cordate lectin (ACL), and Wasabia japonica lectin (WJL), was examined by frontal affinity chromatography using a panel of fluorescently labeled 47 oligosaccharides. The results indicate that BLL recognizes an agalacto structure of the biantennary chain and its bisecting structure. ACL showed strong a...
متن کاملStructures and binding specificity of galactose- and mannose-binding lectins from champedak: differences from jackfruit lectins.
Galactose-binding and mannose-binding lectins from the champedak fruit, which is native to South-east Asia, exhibit useful potential clinical applications. The specificity of the two lectins for their respective ligands allows the detection of potential cancer biomarkers and monitoring of the glycosylated state of proteins in human serum and/or urine. To fully understand and expand the use of t...
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 کاملFructokinases from developing maize kernels differ in their specificity for nucleoside triphosphates.
A new form of fructokinase has been identified from developing maize (Zea mays L.) kernels that utilizes CTP, UTP, and GTP from four to eight times more effectively than ATP at nonlimiting concentrations. Ten millimolar dithiothreitol was necessary to stabilize activity. A second form of fructokinase was nonspecific for nucleoside triphosphate whereas a third form was fairly specific for ATP.
