The power of chemical synthesis of large cysteine-free polypeptides has been significantly enhanced through the use of nonproteogenic constructs which bear strategically placed thiol groups, enabling native chemical ligation. Central to these much expanded capabilities is the specific, radical-induced, metal-free dethiolation, which can be accomplished in aqueous medium.
