A novel protein, LcrQ, involved in the low-calcium response of Yersinia pseudotuberculosis shows extensive homology to YopH.

Journal of bacteriology - 1 May 1992

Rimpiläinen M, Forsberg A, Wolf-Watz H

Abstract excerpt

The plasmid-encoded yop genes of pathogenic yersiniae are regulated by the environmental stimuli calcium and temperature. A novel protein, LcrQ, which exhibits a key function in the negative calcium-controlled pathway, was identified. DNA sequence analysis revealed that LcrQ has a molecular mass of 12,412 daltons and its isoelectric point is 6.51. Overexpression of LcrQ in trans in wild-type Yersinia...
