a The sequence alignments of NascB, NascF5053, and NasS1868. The identical N-terminal and C-terminal parts of NascB/NasF5053 and NasF5053/NasS1868 are shaded in orange and light green, respectively. Residues less important are not shown and indicated by dashed lines. The four critical residues are bolded and highlighted by colors. b In vitro characterization of P450s and their mutants using cWL-PL as substrate.
