Part Description

LP262492-4   Escherichia coli enterotoxigenic stb gene
Enterotoxigenic Escherichia coli (ETEC) produces a heat-labile (LT) and a heat-stable (ST) enterotoxin, both of which cause severe diarrhea in both humans and animals. ST is an extracellular toxin which is comprised of a methanol-soluble (STa) toxin and a methanol-insoluble (STb) toxin. The sta gene encodes the STa toxin and the stb gene encodes the STb toxin. [UniProt:Q70Q79]; [UniProt:Q70Q73] STa combines to its enterocyte receptor, guanylate cyclase, which causes intestinal secretion and diarrhea.[PMID:8528070] The STb enterocyte receptor is the protein sulfatide. After STb binds to sulfatide, it is engulfed by the enterocyte. It then activates the pertussis toxin-sensitive G protein which opens the ligand-gated calcium ion channel, allowing an influx of calcium ions. A subsequent secretion of chloride ions, stimulation of arachidonic acid release, and production of prostaglandin E2 and 5-dyroxytryptamine leads to an efflux of water, bicarbonate ions, sodium ions, and chloride ions into the intestinal space, all of which leads to watery diarrhea.[PMID:23716609] Source: Regenstrief LOINC
