A 26 kDa protein of helicobacter pylori shows alkyl hydroperoxide reductase (AhpC) activity and the mono-cistronic transcription of the gene is affected by pH.

Abstract excerpt

The 26 kDa protein of Helicobacter pylori, with 67% amino acid identity to alkyl hydroperoxide reductase (AhpC) of Campylobacter jejuni, was studied. We wanted to evaluate it the protein has AhpC activity. Therefore, an Escherichia coli mutant defective for alkyl hydroperoxide reductase and a plasmid expressing the 26 kDa protein from H. pylori were used in complementation studies. The complemented E. coli mutant...
