Cholera receptor
WebThe receptor was identified as the ganglioside GM1 (galactosyl-N-acetylgalactosaminyl [sialosyl] lactosyl ceramide), and the results suggested that penetration of the toxin molecule into the membrane follows the rapid binding to GM1. WebAs analyzed with cholera toxin, the polystyrene- adsorbed ganglioside was structurally specific in binding; i.e. only GM1 was active while after hydrolysis by V'ibrio cholerae sialidase also GDla, GDlb and GTlb, for example, had the same activity as GMI. The affinity of cholera toxin for polystyrene-adsorbed GM1 was similar to that
