摘要
Cold shock induction of cspB has been shown to be primarily regulated at the mRNA level. were, we demonstrate that the induction of cspB at low temperature also requires the translational cis-acting element called the downstream box (DB). Full induction of cspB at low temperature is achieved in the presence of both the Shine-Dalgarno sequence and DB. We propose that the DR sequence functions as a translational enhancer for the biosynthesis of CspB to bypass the inhibitory effect in translation caused by cold shock.
