FIG. 4.
Map of the C. crescentus skgA locus. The XhoI-HindIII and HindIII-HindIII fragments were subcloned from the original cosmid. EagI and PstI sites mark the ends of the sequenced region (dashed line) submitted to GenBank (accession no. AF170912) and are not unique sites. The Tn5 insertion site is designated by an arrowhead. The 5′ end of mutL was placed by assuming equal lengths for the C. crescentus and E. coli homologues.
