WebIncubation of human epithelial cells with nanomolar concentrations of chromatographically purified Serratia marcescenshemolysin (ShlA) caused irreversible vacuolation and subsequent lysis of the cells. Vacuolation differed from vacuole formation byHelicobacter pylori VacA. Sublytic doses of ShlA led to a reversible depletion of intracellular ATP. …
Web16 dec. 2009 · The ShlA hemolysin has cytolytic and contact-dependent hemolytic activity, but little is known about the S. marcescens secreted hemolysin. The gene … WebVia site directed mutagenesis, an hemolytic negative isogenic Serratia strain was generated to point out the importance of hemolysin production. RESULTS: We identified an important bacterial factor mediating the internalization of S. marcescens, and lysis of epithelial cells, as the secreted cytolysin ShlA.
Web12 feb. 2014 · These proteins, known as TpsB, are shown to be required for secretion of two model proteins, the S. marcescens hemolysin ShlA (Hertle, 2002. Hertle R.

ShlA is the hemolysin proper, and ShlB transports ShlA through the outer membrane, whereby ShlA is converted into a hemolysin. Superhemolytic ShlA derivatives that displayed 7- to 20-fold higher activities than wild-type ShlA were isolated. gabby nicholas media cabinetWebTpsA components are the passenger proteins (including the ShlA hemolysin and CdiA proteins) and TpsB components are the cognate translocator proteins (including ShlB and CdiB proteins).
