The E.coli glnHp2 (shown from –28 to +3) and S.meliloti nifH (shown from –29 to +3) promoter sequences used for the in vitro transcription assays. The –13GC (for the glnHp2 promoters) and –14GC (for the nifH promoter) promoter elements are underlined and the consensus G is shown in bold. The K.pneumoniae glnAp2 promoter sequence (from –28 to +3) is also given for comparison.
