Photosynthetic Energy Transduction
NREL's photosynthetic energy transduction research explores how natural photosynthesis controls the interactions, assemblies, and reactivities of molecular components coordinating light-generated electron flow with electron utilization in reduction-oxidation reactions and pathways.
Main Research Thrusts
Molecular Control of Light Capture and Electron Flux
We seek to define the compositions and structures of photosynthetic reaction centers and reaction center complexes to understand how these properties determine their function in light capture and electron flow and how function corresponds to electron utilization by available reduction-oxidation pathways.
Electron Transfer and Reduction-Oxidation Enzymes
We seek to understand the electron transfer and catalytic mechanisms of photosynthetic metalloenzymes and how their reactivities are coupled to electron transfer within biochemical pathways.
