Summary
A yqjA yghB double mutant has a membrane defect causing a cell division defect at low temperatures and an osmoremedial growth defect at elevated temperatures (Thomkins, 2008). [More information is available at EcoGene: EG12740]. YqjA is a member of the DedA family of inner membrane proteins . [More information is available at EcoCyc: G7609].

  2. study found that yqjA promoter activity was highest at alkaline pH. Increased activity of the yqjA promoter required both the transcriptional regulator CpxR, in agreement with previous results, and sodium or potassium salts at alkaline pH.

  3. discovery of 2 conserved predicted membrane-embedded arginines (R130 and R136) that are critical for function in both YqjA and YghB; lysine can substitute for arginine at position R130 indicating a charge dependence at this position, but could not substitute at R136; study provides mechanistic insight into YqjA and YghB and supports the hypothesis that they function as membrane transporters
