Abstract excerpt
Heterodimeric binary (Bin) toxin, the major insecticidal protein from Bacillus sphaericus, acts on Culex quinquefasciatus larvae through specific binding to the midgut receptor Cqm1, a role mediated by its 448-amino-acid-long BinB subunit. The molecular basis for receptor recognition is not well understood and this study attempted to identify protein segments and amino acid motifs within BinB that are required...
