Genes encoded in the lps locus exhibit altered Codon Usage Pattern (CUP). Eight amino acids, each of which has atleast four synonymous codons, are represented on the X-axis. The % of codons ending with G/C for each of these amino acids is represented on the Y-axis as mean ± SD. The lower line represents CUP for eight aminoacids of the six genes (excluding transposase ORFs) encoded in the lps locus. The upper line represents CUP of six Xoo genes from elsewhere in the genome (Please refer Methods).
