  Many members of the monocot mannose-binding lectin family, characterized by specificity towards mannose have been characterized and cloned. A majority of these lectins molecules contain 1-4 polypeptides of about 110 residues each. From the previously solved crystal structures of a few such lectins, mostly from non-edible plants, these lectins are thought to possess a common β-prism II fold structure. The major tuber storage protein of Colocasia esculenta is a monocot mannose-binding, widely used, dietary lectin. This tuber agglutinin contains two polypeptides of 12.0 and 12.4 kDa by matrix assisted laser desorption ionisation time-of-flight mass spectrometry. By gel filtration at pH 7.2, the purified lectin has a α2β2 form of apparent molecular mass of 48.2 kDa in solution but at pH 3, it has the heterodimeric αβ form. L.. View More»
