Figure 5: Functional integration of SPs with photoenzymatic activity.
From: Terminal supraparticle assemblies from similarly charged protein molecules and nanoparticles
(a) Formation of nitrite for SP-nicotinamide adenine dinucleotide phosphate (NADPH)-nitrate reductase (NRed) (red) excited at 470 nm and for NADPH-NRed (green) and SP-NADPH-NRed in dark (blue). Inset: formation of nitrite for NADPH-NRed being excited at 470 nm in presence of only one of SP components: either CdTe NPs (black) or CytC (purple) when no hybrid SPs were formed. Errors bars are based on triplicate experimental measurements. (b) Schematics of the reactions on the photoexcitation of SP-NADPH-NRed. Nitrate reductase is represented as a surface model from PyMol software, PDB entry is 2BIH. TEM images of (c) SP-NADPH-NRed after 20 min and (d) after 40 min of the photoenzymatic reaction. Scale bar, 100 nm.
