摘要

光生物催化是一种整合了光催化和生物合成的强大合成策略，能够驱动许多非天然反应。然而，其规模化应用受限于酶载量高、辅因子昂贵以及反应稳定性差等问题。近期，伊利诺伊大学厄巴纳-香槟分校的赵惠民团队利用合成生物技术成功将光酶反应整合到细菌的代谢通路中，构建了首个能够通过发酵放大生产非天然产物的大肠杆菌“生产工厂”。该技术成功实现了对苯酚-吲哚类化合物4-［2-（3

，7

-二氢-1

-吲哚-3-基）乙基］苯酚（DIEP）的完全生物合成。该研究不仅展示了光酶反应在活细胞中实现完全生物合成和工程化放大的可能性，还验证了所合成的非天然产物具有生物活性，这表明该技术具有

工业应用潜力。本文将介绍该研究成果，并结合相关研究工作提出见解，以期推动光生物催化从概念验证迈向工业生产。

Abstract

Photobiocatalysis is a synthetic strategy that integrates photocatalysis and biosynthesis

which has a capacity to drive the biosynthesis of non-natural products. However

its large-scale application is constrained by challenges such as high enzyme loading

the consumption of 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 this regard by successfully integrating photoenzymatic reactions into bacterial metabolic pathways. This pioneering advancement

responded highly in the scientific community

has established the first “

E. coli

production factory” capable of amplifying the production of unnatural products through the fermentation process

and has demonstrated to be capable of synthesizing the phenol-indole compound 4-[2-(3

-dihydro-1

-indol-3-yl)ethyl

]

phenol (DIEP) in its complete biosynthetic route

which not only highlights 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 its potential for industrial applications. The present paper comments on the research findings and offers insights on related studies

with a view to advancing photobiocatalysis from the proof-of-concept stage towards industrial production.
