Table 1 Description of main features of the parachlamydial 100-kb genomic island. Chromosome location of direct repeats, tRNA genes, tra operon, transposases, bacteriophage-related proteins and proteins involved in DNA metabolism is listed below.

From: A genomic island present along the bacterial chromosome of the Parachlamydiaceae UWE25, an obligate amoebal endosymbiont, encodes a potentially functional F-like conjugative DNA transfer system

  1. a, according to Horn et al. [14];
  2. b, positive strand (cooriented as the majority of the genes of the GI); gly-tRNA s are separated by 88 nt;
  3. c, identified by BLAST [35; 36] and CLUSTALW [39] by ourselves;
  4. d, phage-related protein based on additional BLAST hit;
  5. e, partially annotated by Horn et al. [14] and further characterized by ourselves by BLAST [35, 36].
