  • Title: Circular dichroism and fluorescence investigations on Vicia faba lectin-saccharide binding.
    Author: Datta PK, Basu PS, Datta TK.
    Journal: Biochem J; 1988 Apr 01; 251(1):195-9. PubMed ID: 3390154.
    Abstract:
    Vicia faba lectin contained 40-57% beta-conformation, 4-23% alpha-conformation along with random coil at pH 7.2 depending upon the analytical methods used. The percentage of beta-conformation increased with the addition of N-acetyl-D-glucosamine or methyl alpha-D-mannopyranoside. The structural transitions of V. faba lectin were affected by alkali at pH 9.6 and 10.6. Binding constants and free energy changes for the interaction between V. faba lectin and N-acetyl-D-glucosamine and methyl alpha-D-mannopyranoside were estimated at pH 7.2 using the c.d. and fluorescence methods.
