Natural competence for DNA transformation in <i>Helicobacter pylori</i> : identification and genetic characterization of the <i>comB</i> locus

Abstract excerpt

The gram-negative bacterial pathogen Helicobacter pylori, an important aetiological agent of gastroduodenal disease in humans, belongs to a group of bacterial species displaying competence for genetic transformation. Here, we describe the comB gene locus of H. pylori involved in DNA transformation competence. It consists of a cluster of four tandemly arranged genes with partially overlapping open reading frames,...
