Researchers at Tokyo University of Science have re-engineered the CYP107J1 enzyme from Bacillus subtilis to function without redox partner proteins, significantly increasing its catalytic activity. This breakthrough could enhance the sustainability of industrial oxidation processes used in manufacturing pharmaceuticals and dyes.
- 01CYP107J1, a previously uncharacterized enzyme, was modified to operate independently of redox partners.
- 02The engineered enzyme exhibited a 28-fold increase in catalytic activity for 4-hexylbenzoic acid compared to its natural form.
- 03The new form of CYP107J1 can convert indole into indigo, a valuable blue dye, outperforming existing P450 peroxygenases.
- 04This research, led by Professor Toshiki Furuya, offers a method to unlock the potential of other orphan P450 enzymes.
- 05The findings may lead to more sustainable industrial processes by utilizing biocatalysts under mild conditions.

A research team from Tokyo University of Science, led by Professor Toshiki Furuya, has successfully re-engineered the CYP107J1 enzyme from Bacillus subtilis to enhance its catalytic efficiency without the need for redox partner proteins. This modification resulted in a 28-fold increase in activity for oxidizing 4-hexylbenzoic acid. The team also discovered that the new enzyme variant could convert indole into indigo, a commercially significant blue dye, at a rate surpassing existing P450 peroxygenases. Their approach simplifies the catalytic mechanism of the enzyme, making it easier to study enzymes with unknown functions and apply them as effective catalysts for synthesizing useful compounds. This breakthrough could significantly improve the sustainability of industrial oxidation processes, which traditionally rely on harsh conditions and toxic agents. The research highlights the potential for further exploration of other orphan P450 enzymes in various applications, paving the way for greener manufacturing practices.
