The invention belongs to the technical field of biological
catalysis, and relates to a light-driven P450 catalytic
system and application thereof in
pravastatin synthesis. The
system comprises a
thylakoid membrane, Fdx, P450sca-2 and PC / Cyt C6, and is characterized in that the PC / Cyt C6 is connected with the Fdx; the
thylakoid membrane takes H2O as an
electron donor under an illumination condition, electrons are generated through a light
system II, and the electrons are sequentially transferred to Fdx and are conveyed to P450sca-2 through interaction between proteins to catalyze an enzymatic reaction. According to the invention,
light energy and / or water are / is used as an
energy source and an
electron source, expensive NAD (P) H is completely or partially replaced, and the production cost is greatly reduced. The system lays a certain foundation for constructing a P450
reaction system for
photosynthesis and CO2 fixation in the future.
