WebEscherichia coli cytolysin A (ClyA) is an α-helical pore-forming toxin (PFT) which lyses target cells by forming membrane permeabilizing pores. The rate-determining step of this process is the conversion of the soluble ClyA monomer into a membrane inserted protomer. We elucidate the mechanism of this conformational transition using molecular dynamics … WebThe cytolysin, but not the protease, seemed to be important for causing damage in the alimentary tract of the mice.

Cytolysin refers to the substance secreted by microorganisms, plants or animals that is specifically toxic to individual cells, in many cases causing their dissolution through lysis. Cytolysins that have a specific action for certain cells are named accordingly. For instance, the cytolysins responsible for the destruction of red blood cells, thereby liberating hemoglobins, are named hemolysins, and so on. Cytolysins may be involved in immunity as well as in venoms. WebMar 11, 2009 · Cytolysin A (ClyA, also known as HlyE), an alpha-PFT, is a cytolytic -helical toxin responsible for the haemolytic phenotype of several Escherichia coli and Salmonella enterica strains.
