Operons for the non-homologous end-joining proteins. The Ku and ligase D open reading frames are transcribed in the opposite direction to each other on the chromosome in M. marinum (A) and M. tuberculosis (B). The chromosome nucleotide numbers are from Strain M for M. marinum (Refseq number NC 010612) and from H37Rv for M. tuberculosis (Refseq number NC 000963).
