Abstact

A de novo designed intramolecular disulfide bond in myoglobin, resembling that in cytoglobin without structural evidence, was confirmed by an X-ray structure for the first time and was demonstrated to regulate both the structure and function of this protein, which fulfills the design of an artificial dehaloperoxidase, with an activity exceeding that of a native enzyme.
