Pseudomonas aeruginosa encodes an additional DksA paralog (DksA2) that is expressed selectively under Zn(2+) limitation. Although DksA2 does not bind Zn(2+), it complements the Escherichia coli dksA deletion and has similar effects on transcription in vitro. In this study, structural and biochemical analyses reveal that DksA2 has a similar fold, domain structure and RNA polymerase binding properties to those of the E. coli DksA despite the lack of the stabilizing metal ion.
