The refolding of denatured proteins with complete sequences may not be fast enough to account for the in vivo folding of growing peptide chains during biosynthesis. As some peptide fragments have secondary structures not unlike those of the corresponding segments in the intact molecules and native disulfide bonds of some proteins can form cotranslationally, it is suggested that the folding of the nascent chain begins early during synthesis. However, further adjustments may be necessary during chain elongation and after posttranslational modifications of the completed peptide chain to generate the native conformation of a biologically active protein.
