title: The DamX protein of Escherichia coli and Salmonella enterica.
abstract: We recently showed that disruption of damX causes bile sensitivity in Salmonella enterica. The damX gene is part of an operon that contains genes with heterogeneous functions: DNA adenine methylation, biosynthesis of aromatic compounds, carbohydrate metabolism, and tRNA charging. The damX gene encodes a protein with a predicted size of 46 kDa. In Salmonella, DamX is found in the inner membrane of both dividing and non-dividing cells. The DamX protein contains a peptidoglycan-binding SPOR domain, and accumulates in the E. coli septal ring. E. coli mutants lacking DamX are bile-sensitive like their Salmonella counterparts.
