Experimental Process

Genes involved in myo-Inositol catabolism identified by transposon mutagenesis and DNA-array assays. Represssion of target genes shown by beta-gal assays with iolR mutant. Putative motif identified by MEME, then verified with beta-gal with site-directed mutagenesis.

Transcription Factor Binding Sites


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.
