These movements added to the Ai Chi sequence or used separately, depending on the case.
The last predict recombination site is very similar to the Chi sequence (GCTGGTGG), which locally increases recombination in Escherichia coli and is merged of CAGGTG, a predicted recombination site from hypothetical progenitors and RO33 and MAD20 haplotypes of P.
One of them is very similar to the Chi sequence, which locally increases recombination in Escherichia coli [32].
In addition, we used the most recent reference sequences (mentioned above) to perform an updated bioinformatics survey of the Chi sequence (5'GCTGGTGG-3') for the CYP21 genes.
We found no exact match for a Chi sequence throughout the CYP21 genes; however, we did find a Chi-like sequence (1 mismatch in 5'-GCTGGTGG-3') at 6 sites within or in the vicinity of intron 2 (Fig.
