YopD and LcrH regulate expression of Yersinia enterocolitica YopQ by a posttranscriptional mechanism and bind to yopQ RNA.

Journal of bacteriology - 1 Mar 2002

Anderson Deborah M, Ramamurthi Kumaran S, Tam Christina, Schneewind Olaf

Abstract excerpt

Pathogenic yersiniae secrete 14 Yop proteins via the type III pathway. Synthesis of YopQ occurs when the type III machinery is activated by a low-calcium signal, but not when the calcium concentration is above 100 microM. To characterize the mechanism that regulates the expression of yopQ, mutants that permit synthesis of YopQ in the presence of calcium were isolated. Yersiniae bearing deletion mutations in yopN,...
