Figure 1From: Binding specificity of Bacillus thuringiensis Cry1Aa for purified, native Bombyx mori aminopeptidase N and cadherin-like receptorsSeparation of Bombyx mori aminopeptidase N and cadherin-like receptor from solubilized BBMV proteins by anion-exchange chromatography. (A) The absorbance units at 280 nm (AU280) are indicated at left. At right, the percent of buffer B (% NaCl) and actual salt conductivity (% cond) of line traces are shown. Colored fractions denote: yellow, fractions with APN enzymatic activity, but without Cry1Aa-binding ability (24–25 and 30–31); green, fractions with both APN enzymatic activity and Cry1Aa-binding ability (33–36); and blue, fractions that have Cry1Aa binding but no APN activity (26–27).Back to article page
