Two lectins were purified from tuberous roots of Trichosanthes japonica. The major lectin, which was named TJA-II, interacted with Fuc alpha 1-->2Gal beta/GalNAc beta 1-->groups, and the other one, which passed through a porcine stomach mucin-Sepharose 4B column, was purified by sequential chromatography on a human alpha 1-antitrypsin-Sepharose 4B column and named TJA-I. The molecular mass of TJA-I was determined to be 70 kDa by sodium dodecyl sulfate gel electrophoresis. TJA-I is a heterodimer… CONTINUE READING
