The composition, circular dichroism (CD) and N‐terminal amino acid sequence of the lectin from Bauhinia purpurea , a member of the Caesalpinioideae subfamily, are reported. The lectin has one cysteine residue and the CD in the aromatic region is unusually high for plant lectins. The N‐terminal sequence shows much stronger homology to that of another Caesalpinioideae lectin Griffonia simplicifolia GSI than to sequences of Papilinoideae lectins. However, its composition and CD differ from those of GSI, which more closely resemble those of Papilinoideae lectins of similar specificity.
