The oxidation rate of high-potential c-type cytochrome in the photochemical reaction centre is temperature-independent.
The temperature dependence of laser-induced (694.3 nm, 30 ns, 10 mJ.cm-2) high-potential cytochrome c (Em=+290 mV) oxidation kinetics was studied in Ectothiorhodospira shaposhnikovii chromatophores. It was shown that the rate constant of this reaction is independent of temperature in the range of 300 K to 120 K.
