KdpD activity measured with the levels of expression of the Pkdp::lacZ fusion in strains grown in Pi-limiting medium. The strains harbored the kdpD ⁺ [ENZ2337 (circle, square, times symbol); ENZ2363 (plus symbol)] and the kdpD460 alleles [ENZ2360 (triangle, inverted triangle, diamond)]. The symbols represent independent experiments. The values were determined between 5 and 24 h of incubation (circle, square, triangle, inverted triangle) or after 24 h of incubation (times symbol, plus symbol, diamond)
