Abstact

[Image: see text] Rational design of functional enzymes with high turnovers is a significant challenge, especially those with complex active site and difficult reactions, such as in respiratory oxidases. Introducing 2 His and 1 Tyr into myoglobin resulted in designed enzymes that reduce O2 to H2O with > 1000 turnovers and minimal release of reactive oxygen species. This also showed that presence and positioning of Tyr, not Cu, are critical for activity.
