Figure 4

Photoinduced CO2 reduction by [1]-labeled Az variants compared to free [1] in solution. Symbols correspond to labeled CuAz variants (diamonds), labeled ZnAz variants (squares), unlabeled proteins (circles) and free [1] (triangles), with color scheme consistent with that in Figure 3. (A) CO produced (left) and turnover number per protein (TON, right) in the first two hours of the assay. (B) Photocatalytic mechanism for CO2 reduction using [RuII(bpy)3]2+ as a phototrigger. (C) Corrected values for enzyme turnover number over five hours considering the 40% labeling efficiency of Az.
