  • Title: Isolation of a novel legumin-like lectin with potent hemagglutinating activity from seeds of the Chinese chestnut Castanea mollisima.

    Abstract:
    A novel mannose- and glucose-specific lectin with high hemagglutinating activity was isolated from seeds of the Chinese chestnut Castanea mollisima. The lectin possessed a molecular mass of 140 kDa and was made up of two subunits, one with a molecular mass of 31 kDa and another with a molecular mass of 32 kDa. They exhibited substantial homology in N-terminal sequence to the storage protein legumin. The lectin was unstable in the presence of acid and alkali and at temperatures above 50 degrees C, but it was unaffected by various salts. The lectin was purified with a procedure involving ion exchange chromatography on CM-Sepharose, Q-Sepharose and Resource Q and gel filtration on Superose 12.
