Influence of auxiliary YkuN on CYP109B1 catalysis driven by the different YkuN-Fpr fusion constructs. Myristic acid conversion with CYP109B1 (1 µM) was carried out in the presence of the different Ykun-Fpr fusion constructs either in the absence (- YkuN) or presence of additional YkuN (4 or 9 µM). In all cases reactions were started by the addition of a mixture of NADPH and myristic acid and allowed to proceed for 120 min under the support of an NADPH regenerating system. The Fpr/YkuN/CYP109B1 system reconstituted at 1:10:1 and 1:1:1 ratio, respectively achieved 96% and 60% conversion of myristic acid in 120 min.
