FIG 5.

CACHE domains of chemoreceptors that recognize pyruvate and acetate. (A) Structure of a CACHE-type LBD of an uncharacterized chemoreceptor from Vibrio parahaemolyticus (PDB 4EXO) in complex with pyruvate. (B) Structure of a CACHE-type LBD of an uncharacterized chemoreceptor from Anaeromyxobacter dehalogenans in complex with acetate (PDB 4K08). (C) Homology model of the McpP LBD. The model was generated using Phyre² (46). Ninety-one percent of the McpP LBD residues were modeled at >90% confidence.
