[Effect of freezing and thawing on the structure and function of cytochrome oxidase]
Abstract:
The effect of freezing-thawing on cytochrome oxidase from cattle heart was studied. The enzyme was characterized for its activity, absorption spectra, temperature perturbation differential spectra and conformational transitions. A decrease in the activity and conformational changes depend on the composition of the buffer system and the presence of potassium and sodium chlorides in the solution.
