“…Expression of these structural genes depends on another operon, kdpDE. The kdpFABC and kdpDE are collectively called the kdp regulon (Muntyan et al, 2020). The kdpA, kdpB, kdpC, kdpD, kdpE, and kdpF are associated with K+ binding/transport, ATP hydrolysis, catalytic chaperone activity, structural integrity, sensor kinase activity, and response regulation, respectively (Kixmüller, 2011).…”
