evolution
while the GacS/GacA two-component system is widely distributed throughout the bacterial kingdom, the molecular switch formed by the hybrid LadS, PA1611 and RetS histifine kinases is unique to the Pseudomonas species, though it can function in very different ways in phylogenetically related Pseudomonas species
malfunction
gacS or gacA mutations are epistasic to ladS mutation
physiological function
physiological function
in response to environmental changes, Pseudomonas aeruginosa is able to switch from a planktonic (free swimming) to a sessile (biofilm) lifestyle. The two-component system GacS/GacA activates the production of two small non-coding RNAs, RsmY and RsmZ, but four histidine kinases, RetS, GacS, LadS and PA1611, are instrumental in this process. RetS hybrid histidine kinase blocks GacS unorthodox histidine kinase autophosphorylation through the formation of a heterodimer. PA1611 hybrid histidine kinase, which is structurally related to GacS, interacts with RetS in Pseudomonas aeruginosa in a very similar manner to GacS. LadS hybrid histidine kinase phenotypically antagonizes the function of RetS by a mechanism that has never been investigated. The four sensors are found in most Pseudomonas species but their characteristics and mode of signaling may differ from one species to another. In Pseudomonas aeruginosa, LadS controls both rsmY and rsmZ gene expression and this regulation occurs through the GacS/GacA two-component system. In contrast to RetS, LadS signals through GacS/GacA without forming heterodimers, either with GacS or with RetS. Enzyme LadS is involved in a genuine phospho relay, which requires both transmitter and receiver LadS domains. LadS signaling ultimately requires the alternative histidine-phosphotransfer domain of GacS. LadS histidine kinase forms, with the GacS/GacA two-component system, a multicomponent signal transduction system with an original phosphorelay cascade, i.e. H1LadS -> D1LadS -> H2GacS -> D2GacA. This highlights an original strategy in which a unique output, i.e. the modulation of sRNA levels, is controlled by a complex multi-sensing network to fine-tune an adapted biofilm and virulence response. H1 and D1 domain involvement of the LadS hybrid histidine kinase in the LadS signaling pathway, and involvement of the H2 domain of the GacS unorthodox histidine kinase in the LadS signaling pathway, overview

In vitro transphosphorylation of GacS H2 domain by LadS histidine kinase, involvement of the H2 domain of the GacS unorthodox histidine kinase in the LadS signaling pathway
physiological function
a GacS mutant devoid of the periplasmic detector domain is severely defective in biofilm formation accompanied by concomitant changes in the expression of small RNAs RsmY/Z that control activation of GacA-regulated genes. Point mutations in a putative ligand binding pocket lined by positively-charged residues originating primarily from the major loop impair biofilm formation
physiological function
free-standing PilZ protein PA2799 interacts directly with the histidine kinase SagS. PA2799 binds directly to the phosphoreceiver domain of SagS, and the SagS-HapZ interaction is further enhanced at elevated c-di-GMP concentration. Binding of HapZ to SagS inhibits the phosphotransfer between SagS and the downstream protein HptB in a c-di-GMP-dependent manner. HapZ impacts surface attachment and biofilm formation most likely by regulating the expression of a large number of genes
