摘要

The ability to identify sequences in a randomly encoded polypep- tide library that are capable of acquiring unique and stably folded structures would be valuable in the examination of protein-folding issues. The quality control system of the yeast secretory pathway prevents the release of incompletely folded polypeptides. Earlier work has shown that this feature can be used in a screen to identify mutations that increase the stability of a protein. We sought to extend this strategy for use with random sequence libraries by combining a quality-control system-based screen with generic tag-based immunodetection that can be applied to any sequence.
