catalytically self-sufficient enzymes. However, the connection between the different
functional modules should allow a certain degree of flexibility in order to obtain functional
and catalytically efficient proteins. We previously applied the molecular Lego approach to
develop a chimeric P450 3A4 enzyme linked to the reductase domain of P450 BM3 (BMR).
Three constructs were designed with the connecting loop containing no glycine, 3 glycine or …
