title: Effect of helium-neon laser on activity and optical properties of catalase.
abstract: The effects of laser (632.8 nm) on functional and spectral properties of catalase at pH 6.0-7.4 were studied. Laser irradiation led to photoactivation of the enzyme at pH 7.1-7.4. Changes in the spectral properties of photomodified hemoprotein were found in the absorption spectrum of the protein component: apoenzyme displayed protective effects in relation to ferroporphyrin. Structural modifications of catalase induced by helium-neon laser irradiation correlated with its functional properties. These results can be used in clinical practice to design the individual management program.
