CheB 352 (408) 206 (249) 19 17
CheR 340 (395) 206 (251) 44 42

  1. Numbers in brackets refer to homologues found in all 523 bacterial genomes examined. All other numbers are taken from those species with at least one of each of the 5 core Che proteins.
  2. *Isolated che genes refer to che genes that are not in close proximity to other che genes.
