Abstract
Stochastic fluctuations of ion current through one chitoporin (ChiP) channel within a bilayer lipid membrane in sugar solution are analyzed. These reflect single-molecule dynamics, which indicate that ChiP has multiple binding sites for sugar and exploits interactions between bound molecules to direct sugar passage. Since ChiP is used by marine bacteria, this is likely an adaptive strategy to enhance sugar translocation from rough water.
