Correlative effect on the toxicity of three surface-exposed loops in the receptor-binding domain of the Bacillus thuringiensis Cry4Ba toxin.

Abstract

Surface-exposed loop residues, Pro(389) (beta(6)-beta(7) loop), Glu(417) (beta(8)-beta(9) loop), Tyr(455) and Asn(456) (beta(10)-beta(11) loop), in the receptor-binding domain of the Bacillus thuringiensis Cry4Ba toxin have been previously demonstrated to be crucial for toxicity. Herein, five combinations of two-loop mutants, P389A/E417A (beta(6)-beta(7… (More)
