Enzyme activity assay of PdcDE. (a) Absorbance readings from 250 nm to 320 nm in the absence of His6-PdcDE; (b) Spectral changes during rapid oxidation of HQ by purified His6-PdcDE. The spectra were recorded a total of five times over a five minute period (marked 1-5). The arrows indicate the direction of spectral changes.
