График зависимости скорости реакции от концентрации глюкозы имеет выраженный сигмоидальный характер: при 25°С и 2°С коэффициенты Хилла во всем диапазоне концентраций субстрата равны 1,76 и 1,35; значения S0,5 для глюкозы составляют 6,90 мМ и 20 мМ соответственно. Обсуждается роль кинетического механизма реакции в регуляции активности глюкокиназы в печени.</p></abstract><trans-abstract xml:lang="en"><p>A simple method for purification of glucokinase from soluble fraction of rat liver has been developed which allows to obtain enzyme preparation with high specific activity and native cooperative characteristics practically lacking of contamination of other molecular forms of hexokinase. The dependence of enzyme activity upon glucose concentration shows pronounced sigmoid behavior: at 25°С and 2°С the Hillґs coefficients on whole range of substrate concentration are equal to 1,76 and 1,35, and S0,5 values for glucose are equal 6,9 mM and 20 mM, respectively. The role of kinetic mechanism of the reaction in the regulation of glucokinase activity in liver is discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глюкокиназа</kwd><kwd>гексокиназа</kwd><kwd>кооперативные свойства.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glucokinase</kwd><kwd>hexokinase</kwd><kwd>cooperative properties</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Massa M.L., Gagliardino J.J., Francini F.
