In this study, we have analysed the DNA binding activity of H. pylori replicative helicase, DnaB. While the C-terminal region of HpDnaB is important for its DNA binding activity, the N-terminus masks the DNA binding activity profoundly. The masking effect can be overcome either by deleting the N-terminus or by interaction with a partner like the C-terminus of DnaG primase.
