Overview of repeats in Ana.

(A) Examples of a perfect 26mer GGGGATT repeat patterns in Ana. Repeat #12 is located in an intergenic region in the pec operon between pecE and pecF. (B) Frequency plot [49] shows the consensus nucleotide sequence of heptameric repeat units in Ana. (C) Distribution of GGGGA(T/C)T repeats on the Ana chromosome (NC_003272). Repeats located on the plus strand are marked in blue [38], repeats on the minus strand in red [51]. Locations of repeat associated genes pecE, clpP, lpxB, all3209 and alr4373 have been marked for orientation. (D) Orientation of neighboring genes relative to repeat sequences. Intergenic repeats can be located on the same strand that will serve as the coding strand of the aligned ORFs (dark-blue) or on the non-coding strand (light blue), between convergent (dark green) or divergent (light green) ORFs. Intragenic repeats can be located on the coding strand (dark gray) or non-coding strand (light gray).
