The first column specifies the number given to the different receptors.
^aCR chemoreceptor, GGDEF/EAL diguanylate cyclase/phosphodiesterase, HK histidine kinase, S/T phos serine/threonine phosphatase.
^bLigand binding residues of the dCache_1PU motif are shown. Strands of non-conserved residues between the motif residues are implied according to the motif definition in Fig. 2D.
^cThe corresponding references are provided in Supplementary Table 2.
