The 114-fold anaerobic activation seen for the wild-type dmsA promoter was reduced to about 35-fold in each of the two mutants (Figure 1), indicating that the position of the Fnr site at the wild-type dmsA promoter is important for controlling optimal dmsA gene expression.
The protections are consistent with the proposal that NarL-phosphate recognizes and binds at multiple heptamer recognition sites within the dmsA P1 promoter region.
Therefore, a simple model that accounts for the footprint data is the assembly of multiple NarL-phosphate molecules onto one face of the DNA that somehow protect the minor groove from hydroxyl radical attack [ 28 29 30 ] . In an alternative model, NarL binds only at the three proposed NarL heptamer consensus sites spaced at 20 bp intervals within the dmsA regulatory region (Figure 4).
The fragment extends from position -127 to -13 relative to the start of dmsA transcription at P1 (Figure 4).
Each intended mutation was confirmed by DNA sequence analysis [ 34 ] . A Hinc II/ Bam HI fragment containing the regulatory region was excised from the M13 template and inserted into the plasmid pRS1274 to give the JA250 (wild type) and related mutant dmsA - lac Z promoter fusions (Figure 1).
