The Lectins of Sophora japonica: I. Purification Properties and N-Terminal Amino Acid Sequences of Two Lectins from Leaves.
Two lectins, Leaf Lectin I and Leaf Lectin II (LLI and LLII) were purified from the leaves of Sophora japonica. Like the Sophora seed lectin, LLI and LLII are tetrameric glycoproteins containing a single subunit with respect to size. The subunits of LLI (32 kilodaltons) and LLII (34 kilodaltons) are slightly larger than those of the seed lectin (29.5 kilodaltons). The three Sophora lectins disp...
متن کاملThe Lectins of Sophora japonica: II. Purification, Properties, and N-Terminal Amino Acid Sequences of Five Lectins from Bark.
Five N-acetyl-galactosamine-specific lectins were isolated from the bark of the legume tree Sophora japonica. These lectins are immunologically and structurally very similar, but not identical, to the Sophora seed and leaf lectins. The carbohydrate specificities and hemagglutinin activities of these lectins are indistinguishable at pH 8.5 but their activities differ markedly at pH values below ...
متن کاملPreliminary X-ray diffraction analysis of crystalline lectins from the seeds and leaves of Sophora japonica.
The Japanese Pogada Tree (Sophora japonica) contains at least four distinct lectins distributed among seeds, bark, and leaf tissues of the plant. All of these lectins are N-acetylgalactosamine-specific, have molecular weights of about 130,000, are glycoproteins and possess substantial sequence homology. However, they are products of distinct genes. We have crystallized Sophora lectins from bark...
متن کاملBark and Leaf Lectins of Sophora japonica Are Sequestered in Protein-Storage Vacuoles.
The leguminous tree Sophora japonica contains a family of closely related, but distinct, lectins. Different members of this family are independently expressed in seeds, leaves, and bark (CN Hankins, J Kindinger, LM Shannon 1987 Plant Physiol 83: 825-829; 1988 Plant Physiol 86: 67-10). The inter-, and intracellular distribution of the bark and leaf lectins was studied by indirect postembedding i...
متن کاملIsolation of Antiosteoporotic Compounds from Seeds of Sophora japonica
Chemical investigation of Sophora japonica seeds resulted in the isolation of seven metabolites identified as: genistin (1), sophoricoside (2), sophorabioside (3), sophoraflavonoloside (4), genistein 7,4'-di-O-β-D-glucopyransoide (5), kaempferol 3-O-α-L-rhamnopyranosyl(1 → 6)β-D-glucopyranosyl(1 → 2)β-D-glucopyranoside (6) and rutin (7). Compounds 1, 2 and 5 showed significant estrogenic prolif...
