SOLUTION STRUCTURE OF THE INSECTICIDAL NEUROTOXIN J-ATRACOTOXIN-HV1C
Overview
We have isolated a family of insect-selective neurotoxins from the venom, of the Australian funnel-web spider that appear to be good candidates for, biopesticide engineering. These peptides, which we have named the, Janus-faced atracotoxins (J-ACTXs), each contain 36 or 37 residues, with, four disulfide bridges, and they show no homology to any sequences in the, protein/DNA databases. The three-dimensional structure of one of these, toxins reveals an extremely rare vicinal disulfide bridge that we, demonstrate to be critical for insecticidal activity. We propose that, J-ACTX comprises an ancestral protein fold that we refer to as the, disulfide-directed beta-hairpin.
