Analysis of 12 Helicobacter pylori promoters indicates
the existence of a consensus
10 hexamer (TAtaaT) but
little conservation of
35 sequences. In this study, mutations in
either the H. pylori vacA
10 region or the
35 region
resulted in decreased vacA transcription and suggested that
an extended
10 motif is utilized. Thus, despite the lack of a
35
consensus sequence for H. pylori promoters, the
35 region
plays a functional role in vacA transcription.
