Research ARTICLEA Rhodobacter sphaeroides Protein Mechanistically Similar to Escherichia coli DksA Regulates Photosynthetic GrowthChristopher W.Price of 501015-16-3 Lennon,a Kimberly C.

Gourse,aDepartment of Bacteriologya and DOE Good Lakes Bioenergy Research Center, Wisconsin Power Institute,b University of Wisconsin–Madison, Madison, Wisconsin, USAABSTRACT DksA can be a global regulatory protein that, together with all the alarmone ppGpp, is necessary for the “stringent response” to nutrient starvation inside the gammaproteobacterium Escherichia coli and for extra moderate shifts in between growth conditions. DksA modulates the expression of a huge selection of genes, straight or indirectly. Mutants lacking a DksA homolog exhibit pleiotropic phenotypes in other gammaproteobacteria too. Right here we analyzed the DksA homolog RSP2654 in the additional distantly related Rhodobacter sphaeroides, an alphaproteobacterium. RSP2654 is 42 identical and equivalent in length to E. coli DksA but lacks the Zn finger motif from the E.Indium trichloride,99.99% Price coli DksA globular domain. Deletion on the RSP2654 gene results in defects in photosynthetic development, impaired utilization of amino acids, and an increase in fatty acid content.PMID:24624203 RSP2654 complements the development and regulatory defects of an E. coli strain lacking the dksA gene and modulates transcription in vitro with E. coli RNA polymerase (RNAP) similarly to E. coli DksA. RSP2654 reduces RNAP-promoter complex stability in vitro with RNAPs from E. coli or R. sphaeroides, alone and synergistically with ppGpp, suggesting that even though it has restricted sequence identity to E. coli DksA (DksAEc), it functions within a mechanistically comparable manner. We as a result designate the RSP2654 protein DksARsp. Our function suggests that DksARsp has distinct and important physiological roles in alphaproteobacteria and can be helpful for understanding structurefunction relationships in DksA along with the mechanism of synergy among DksA and ppGpp. Importance The part of DksA has been analyzed mostly within the gammaproteobacteria, in wh.
