[Effect of temperature and composition of frozen solutions on the rate of peroxidase oxidation of 2,3-dimethyl-1,4-naphthoquinol-1-dimethylphosphate].
The horseradish peroxidase-catalyzed oxidation of 2.3-dimethyl-1.4-naphthoquinol-1-dimethylphosphate by hydrogen peroxide was investigated within the temperature range of +20 divided by -35 degrees. The increase in the concentration of the buffer solution accelerated the reaction in liquid solutions at 0 degrees and 20 degrees. The unusual shapes of the curves of temperature dependences of the reaction rate in frozen solutions of different composition can probably be due to temperature variations in some physico-chemical parameters of the system under study.
