Description Two lectins, an N-acetylgalactosamine-binding lectin, lectin-I, which reacts specifically with human
erythrocytes of blood group A, and a galactose-binding lectin, lectin-II, which is specific for
human blood group B erythrocytes, have been isolated and purified from rice bean, Phoseolus calcaratus
syn. Vigna umbellata, by a salt solubility pH-dependent method, chromatofocusing and highperformance
liquid chromatography. The homogeneity of the lectins was determined by liquid chromatography
and polyacrylamide gel electrophoresis. The purified h&in-I of molecular mass 80 000
is possibly composed of two subunits of molecular mass ca. 18 000 and 22 000, respectively, whereas
lectin-II of molecular mass 100 000 appears to be composed of a monomeric protein of molecular mass
25 000. One endogenous lectin-binding protein was also isolated and purified by liquid chromatography.
The endogenous h&in-binding protein of molecular mass 40 000 affects the activity of the
A-group specific lectin more than that of the B-group specific lectin. The endogenous k&in-binding
protein appears to be composed of a monomeric protein of molecular mass 20 000.
