Figure 5. Sequence detail of borders between IR repeats and central sequences.
Borders between repeats and central sequences in the L. delbrueckii ssp. bulgaricus strains 2038, ATCC BAA365 and ATCC11842 are projected on the sequence of the L. delbrueckii ssp. lactis strain NDO2 (which contains no large IR). The ssp. bulgaricus sequences are identical to the corresponding ssp. lactis sequences unless indicated otherwise. Blue arrows, small IR (IRa) in strain NDO2; broken black arrows, imperfect inverted repeat (IRb) in strain NDO2; I, II, and U as in Fig. 3; *region making part of the repeat in strain ATCC11842, but making part of the non-repeated central sequence in strains ATCC BAA365 and 2038. The presented NDO2 sequences are representative for all 5 ssp. lactis strains in this study.
