A mutation in hspQ allows some dnaA(Ts) strains to grow at 40C, and slows the degradation of DnaA508 at 40C. Despite forcing translation at the upstream start, some HspQ(YccV) protein likely initiating at this true start site was observed by d'Alencon et al. (2003). Binding to hemimethylated oriC is specific, but weak, possibly due to the extra 17 N-terminal residues on the purified HspQ(YccV). RpoH regulon.[4]
