  • a +, presence of the gene; −, absence of the gene; P, pseudogene. The analysis was performed by using BLASTX nework services. Genes listed as present were located in the same genetic locus as their M. tuberculosis orthologs and encoded putative proteins at least 68% similar to their M. tuberculosis counterparts.
