Regulated secretion of YopN by the type III machinery of Yersinia enterocolitica.

Journal of bacteriology - 1 Sept 2001

Cheng L W, Kay O, Schneewind O

Abstract excerpt

During infection, Yersinia enterocolitica exports Yop proteins via a type III secretion pathway. Secretion is activated when the environmental concentration of calcium ions is below 100 microM (low-calcium response). Yersiniae lacking yopN (lcrE), yscB, sycN, or tyeA do not inactivate the type III pathway even when the concentration of calcium is above 100 microM (calcium-blind phenotype). Purified YscB and SycN...
