CLASS
NOMEN	LECa.Pha.Vul.xx.Xxxx
INDEX	Lectin from higher animal, typically vertebrates / / / /
CHARACTERIZATION	For characterization of Pinto III, see: Lect. Biol. Biochem. Clin. Biochem. 1982 (2) 743
BIOACTIVITY	agglutinates group A erythrocytes at a titer of 1:256; group B erythrocytes at a titer of 1:256; group B erythrocytes at a titer of 1:256; by crude lectin preparation (16mg/ml). See: Int J Cancer 1970;6:283 Antinutritional factors of anasazi bean were compared to traditional pinto bean (Phaseolus vulgaris L. ). Anasazi beans contained less (p<0.001) soluble and bound condensed tannins compared to pinto beans. No differences (p>0.05) in stachyose and raffinose content were found between the two bean types; verbascose was not detected at all. Significant (p<0.05) differences in lectin content were observed between anasazi and pinto bean. The lectins of anasazi beans were classified as non toxic and those of the pinto beans as toxic types. No differences (p>0.05) in inhibitor activity against human and bovine trypsin and chymotrypsin were found between the two bean types. See: Plant Foods Hum Nutr 1997;51(2):85-98
