Abstract in brief

  • Cyclic diAMP is a crucial second messenger in bacteria and archaea that regulates essential proteins, including potassium transporters like KimA, which helps bacteria manage potassium levels and osmoregulation.
  • The study uses cryoEM structures, functional tests, and molecular dynamics simulations to show how cdiAMP binds to KimA and inhibits its function by trapping it in an inwardoccluded conformation, preventing further potassium transport.
  • This binding occurs through an intracellular loop in KimA that interacts with cdiAMP, reducing the movement of transmembrane helices and effectively halting K+ uptake when potassium levels are sufficient or potentially toxic.]
