A lectin from Wisturi~ floribunda seeds which specifically binds to N-acetyl-bgalactosamine was purified to homogeneity as judged by polyacrylamide gel electrophoresis. Its molecular weight was estimated to be 68,000 by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. It dissociated into subunits on reduction with 2-mercaptoethanol with concomitant loss of hemagglut...

Millettia japonica was recently reclassified into the genus Wisteria japonica based on chloroplast and nuclear DNA sequences. Because the seed of Wisteria floribunda expresses leguminous lectins with unique N-acetylgalactosamine-binding specificity, we purified lectin from Wisteria japonica seeds using ion exchange and gel filtration chromatography. Glycan microarray analysis demonstrated that ...

Concrete infrastructures that make up the sewer system exposed to waste waters are often subjected microbial corrosion. The biogenic sulfuric acid produced by activity of sulfur-oxidizing bacteria A.thiooxidans attacks concrete in sewers leading loss mass and deterioration.The aim this study was control biodegradation using plant extracts Alchornea Cordifolia. samples were corroded for 26 month...
