An investigation of the molecular basis of the spontaneous occurrence of a catalase-negative phenotype in Helicobacter pylori.

Helicobacter - 1 Mar 1998

Manos J, Kolesnikow T, Hazell S L

Abstract excerpt

BACKGROUND: The discovery of a highly active catalase in Helicobacter pylori that in some strains may lose its activity has generated strong scientific interest. We have characterized a spontaneous catalase-negative isolate of H. pylori (UNSW-RU1) and sequenced katA in the parent strain and the promoters of both phenotypes as a prelude to understanding the genetic processes leading to the failure to express...
