Depletion of YqfG results in a dramatic decrease in 70S ribosomes. (A) Sucrose gradients of the wt strain (blue) and the Pspac-yqfG strain (CCB751) grown in the presence (purple) and absence of IPTG (pink). (B) Agarose gels of sucrose gradient fractions from wt and strain CCB751 grown in the presence and absence of IPTG. Polysomal fractions (poly) are indicated.
