FIG. 1.

mutS and mutL genes in Gc strain FA1090. Open reading frames are indicated by open block arrows, which point in the direction of transcription. Names of open reading frames are shown underneath the arrows (hypo, hypothetical protein encoded by NG0745). Solid lines connecting block arrows are predicted intergenic regions. The triangle denotes the position of the mini-Tn5<ERM> transposon insertion in mutS, with the arrow pointing in the direction of Erm transcription. The region deleted in mutL is indicated by the dotted lines. Drawings are to scale. Bar, 500 bp.
