Competition with labeled Cry1Aa and mutant toxins to B. mori brush border membrane vesicles (BBMV) (bars represent error of n = 4). Cry1Aa wild type protein, (â—‹-â—‹); F313A mutant protein, (â—Š-â—Š); F333A-F335A, mutant protein (â–½-â–½); F461A mutant protein, (â—†-â—†); and, F328A mutant protein, (â–²-â–²). % uncompeted toxin indicates the % of labeled toxin remaining bound to BBMV in the presence of unlabeled cold toxin competitor.
