Using the Gibbs Motif Sampler for Phylogenetic Footprinting

OSTI ID:919699
The Gibbs Motif Sampler (Gibbs) (1) is a software package used to predict conserved elements in biopolymer sequences. While the software can be used to locate conserved motifs in protein sequences, its most common use is the prediction of transcription factor binding sites (TFBSs) in promoters upstream of gene sequences. We will describe approaches that use Gibbs to locate TFBSs in a collection of orthologous nucleotide sequences, i.e. phylogenetic footprinting. To illustrate this technique, we present examples that use Gibbs to detect binding sites for the transcription factor LexA in orthologous sequence data from representative species belonging to two different proteobacterial divisions.
