  1. 1. Proteins belonging to the PE/PPE families were extracted to a separate category, as they constitute an important family of proteins in M. tuberculosis.
  2. 2. The genes for the transposase IS6110 were removed from the category of Replication, recombination and repair.
  3. 3. Cumulative length (bp) of all the genes in a given category. The probability of under or over-representation of a given functional category is dependent on both the number of genes and their length.
  4. 4. Represents the number of independent insertion events identified in genes of a given category.
  5. 5. Probability of over or under-representation of insertion sequences interrupting genes of a given category. In bold, categories with significant over-, under-representation after Bonferroni correction. Bonferroni corrected threshold = 2.2E-3.
  6. 6. This category is not part of COG; it is defined in tuberculist (see Methods).
