Abstract
  • Summary. Mutations in ribosomal protein L6 cause (i) loss of viability of cells at 0° C, which can be prevented by the presence of sodium chloride or 20% sucrose in the medium, (ii) influx of compounds at low temperature that normally cannot penetrate, and (iii) a defective assembly and maturation of 30S and 50S subunits at low temperature. It is proposed that abnormal interaction of immature subunits (or mutant 70S ribosomes) with the cytoplasmic membrane is responsible for triggering breakdown of membrane stability during cold shock.
