Abstract

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 8. All five lectins are tetrameric glycoproteins made up of different combinations of subunits of about 30,000, 30,100, 33,000 Mr containing 3% to 5% covalently attached sugar. These lectins are the overwhelmingly dominant proteins in bark, but they do not appear to be present in other tissues. Amino terminal sequence analysis indicates that at least two distinct lectin genes are expressed in bark.
