Phydbac is a web interactive tool that display phylogenomic profiles of bacterial protein sequences. It also provides a way to identify, in a given organism, the proteins that have the most similar sequence conservation profiles to a query protein. The analysis of the annotation of those phylogenomic neighbors may help generate hypothetical functions for the query protein(s). This is the second major release of Phydbac (01/02/2004).
