Photobiocatalysis is a synthetic strategy that integrates photocatalysis and biosynthesis
and has the capacity to drive numerous non-natural reactions. However
its large-scale application is constrained by issues such as high enzyme loading
expensive cofactors
and poor reaction stability. Recently
the research team led by Hui-Min Zhao at the University of Illinois Urbana-Champaign achieved a significant milestone in synthetic biology by successfully integrating photoenzymatic reactions into bacterial metabolic pathways. This pioneering advancement
reported in the scientific community
has established the first "E. coli production factory" capable of amplifying the production of unnatural products through the process of fermentation. This technology has been demonstrated to be capable of synthesising the phenol-indole compound 4-(2-(3a
7a-dihydro-1H-indol-3-yl)ethyl)phenol (DIEP) in its complete biosynthetic form. This research demonstrates not only the feasibility of achieving complete biosynthesis and engineered amplification of photoenzymatic reactions within living cells
but also validates the biological activity of the synthesized non-natural product
indicating the technology's industrial application potential. The present paper sets out the research findings and offers insights based on related studies
with a view to advancing photobiocatalysis from the proof-of-concept stage towards industrial production.
