Randomized trial shows cold shock activates CsdA in E. coli, indicating its role in protein synthesis.

This research investigates the role of the CsdA protein in E. coli under cold shock conditions.
Temperature shift from 37 to 15 degrees C to induce CsdA protein expression.
Isolation and characterization of CsdA localized to the ribosomal fraction.
Analysis of cell growth and protein synthesis post-csdA deletion.
CsdA became a major ribosomal-associated protein upon cold shock at 15 degrees C.
CsdA deletion significantly impaired cell growth and the synthesis of heat-shock proteins.
Purified CsdA unwound double-stranded RNA without the need for ATP.

Jones et al. (1996) studied this question.
