Table 4 Transmitter and receiver domain composition of TCS proteins

From: Genome-wide analysis of myxobacterial two-component systems: genome relatedness and evolutionary changes

% myxobacteria / % bacteria 0 R 1 R 2 R 3 R 4+ R
0 T 0.41 (28) 0.92 (1340) 1.58 (32) 2.13 (2) a(0)

  1. Values are the % of myxobacterial TCS proteins exhibiting the number of receiver (R) and transmitter (T) domains in question divided by the % of all such bacterial TCS proteins [24]
  2. aThere are no such proteins in bacteria
  3. bNo such proteins in myxobacteria (only 0.009 % of all TCS proteins in bacteria have 2+ transmitter and 3+ receiver domains). Numbers of such myxobacterial proteins are shown in parentheses
