RK− ilr mutations characterized within λ genes O-P. The minimal oriλ size was suggested to include a HIGH-AT-rich region to the right of four iteron sequences, ITN’s1-4 [43,44], which each contain an 18 bp inverted repeat of hyphenated symmetry, joined by adenine residues that can cause oriλ to assume a bent structure [45]. The mutants shown designated ori95, ori96 and ori98 were obtained from WD from prophage with r-mutants r-95, r-96, and r-98. Note that Denniston-Thompson, et al., [46] sequenced the r-mutants r-99, r-96 and r93 which represent Δ12 bp (39120–39131), Δ15 bp (39138–39152) and Δ24 bp (39092–39115) [42]. Our sequence localization for ori96 (r96) differs by one bp from that assigned in [42].
