Isolation and characterization of a lectin from the seeds of Dioclea lehmanni.
Affinity chromatography of the globulin fraction from the seeds of Dioclea lehmanni on Sephacryl S-200 yielded two lectins, one slightly retarded and another strongly bound. The latter, which was a glucose/mannose specific lectin, was purified and the following properties were determined: pI, Mr of subunits, carbohydrate content, A, aminoacid composition, hemagglutination and inhibition patterns, N-terminal sequence and mitogenic activity. These properties of the lectin were very similar to those of the Con A and Dioclea grandiflora lectins.
