Comparative organization of prsA-like loci. The prsA-like loci from eight Gram-positive bacteria are shown where arrows represent open- reading frames. Genes with similar functions have the same color while genes that have unrelated functions are in gray. The annotation of genes mentioned in the text: yhaN encodes a putative ATPase involved in DNA metabolism containing a chromosome partition domain (smc), yhaM encodes a 3'-5' exoribonuclease, coiA encodes a competence transcription factor, pep is a peptidase, htr is a transcriptional regulator, and alaS is a alanyl-tRNA synthetase.
