abstract：:Clustered codons that pair to low-abundance tRNA isoacceptors can form slow-translating regions in the mRNA and cause transient ribosomal arrest. We report that folding efficiency of the Escherichia coli multidomain protein SufI can be severely perturbed by alterations in ribosome-mediated translational attenuation. S...
