    Nascent polypeptide chains fold cotranslationally, but the atomic-level details of this process remain unknown. Here, we report crystallographic, de novo modeling, and spectroscopic studies of intermediate-length variants of the λ repressor N-terminal domain. Although the ranges of helical regions of the half-length variant were almost identical to those of the full-length protein, the relative orientations of these helices in the intermediate-length variants differed. Our results suggest that cotranslational folding of the λ repressor initially forms a helical structure with a transient conformation, as in the case of a molten globule state. This conformation subsequently matures during the course of protein synthesis.
