  • a Organisms encoding at least one putative complete DHA PTS are grouped into six categories (A to F) based on the presence of additional complete or incomplete putative DHA PTSs or the presence of a putative ATP-dependent system.

  • b Three-letter abbreviations used in phylogenetic analyses.

  • c The occurrence of all three (DhaK, DhaL, and DhaM) proteins, believed to be required for a PTS-dependent DHA system, as well as additional proteins, is indicated. The number of paralogous proteins encoded in the genome of an organism is indicated in parentheses.

  • d The domains within the DhaM protein are indicated. The EIΔ domain represents a C-terminally truncated PTS enzyme I domain.
