Inhibition of Escherichia coli chemotaxis by omega-conotoxin, a calcium ion channel blocker.

L S Tisa1, B M Olivera, J Adler.   

Abstract

Escherichia coli chemotaxis was inhibited by omega-conotoxin, a calcium ion channel blocker. With Tris-EDTA-permeabilized cells, nanomolar levels of omega-conotoxin inhibited chemotaxis without loss of motility. Cells treated with omega-conotoxin swam with a smooth bias, i.e., tumbling was inhibited.
