Experimental Process

Differentially expressed genes identified by DNA-array. Putative sites identified by MSA with known (algD) promoter sites. Function of site shown by restoration of twitching motility with motility plasmid on a algR mutant.

Gene Regulation

Regulated genes for each binding site are displayed below. Gene regulation diagrams show binding sites, positively-regulated genes, negatively-regulated genes, both positively and negatively regulated genes, genes with unspecified type of regulation. For each indvidual site, experimental techniques used to determine the site are also given.

Site sequence	Regulated genes	Experimental techniques	TF function	TF type
CCGTCGGTC	pilY1, pilX, pilW, pilV, fimU, fimT, pilY2,	Experimental technique details Ad-hoc quantitative phenotype observation (ECO:0005676) Ad-hoc quantitative phenotype observation - ECO:0005676 A quantifiable phenotypic trait (e.g. glucose intake) is assessed in a quantitative manner after induction of the regulatory mechanism and used as a natural reporter.. The observable phenotypic trait should be described in the experimental notes. - Experimental technique details DNA-array expression analysis (ECO:0005525) DNA-array expression analysis - ECO:0005525 DNA-arrays (or DNA-chips or microarrays) are flat slabs of glass, silicon or plastic onto which thousands of multiple short single-stranded (ss) DNA sequences (corresponding to small regions of a genome) have been attached. After performing a mRNA extraction in induced and non-induced cells, the mRNA is again reverse transcribed, but here the reaction is tweaked, so that the emerging cDNA contains nucleotides marked with different fluorophores for controls and experiment. Targets will hybridize by base-pairing with those probes that resemble them the most. The array can then be stimulated by a laser and scanned for fluorescence at two different wavelengths (control and induced). The ratio or log-ratio between the two fluorescence intensities corresponds to the induction level. - Experimental technique details Multiple sequence alignment (MSA) (ECO:0005556) Multiple sequence alignment (MSA) - ECO:0005556 MSA can be used to align promoter regions and highlight regions of conservation that may be indicative of transcription factor binding sites. -	activator	dimer
