Эффективным инструментом в исследовании цитохромов P450 является создание электрохимических систем, где на твёрдом носителе — электроде — с помощью модификатора иммобилизуется фермент. Электроны в таком случае поступают с электрода, заменяющего природный донор электронов НАД (Ф)H и ограничивающего необходимость использования редокс-партнёрных белков. Задача модификатора электрода — сохранение каталитической активности фермента, а также повышение эффективности электронного транспорта при включении наночастиц благородных металлов или углеродных материалов.</p><p>Цель работы — создание более эффективных цитохром Р450 электрохимических систем для увеличения выхода метаболитов ферментативных электрокаталитических реакций. </p></abstract><trans-abstract xml:lang="en"><p>Cytochromes P450 (CYP) are a large class of enzymes, whose active site is type b heme. The main function of cytochromes P450 is biotransformation of endogenous and exogenous compounds in the organism. The cytochrome P450 3A4 metabolizes about 50% of all modern medications; therefore, its catalytic properties present significant research interest. P450 cytochromes can be effectively investigated using electrochemical systems that consist of a solid base (electrode) and a modifier facilitating enzyme immobilization. In this case, the electron donor is an electrode substituting a natural electron donor NAD(P)H and eliminating the need to use redox-partner proteins. The electrode modifier maintains the catalytic enzyme activity and enhances the efficiency of electron transfer when noble metals and carbon materials nanoparticles are included. This work is aimed at creating more effective cytochrome P450 electrochemical systems to increase the yield of metabolites of enzymatic electrocatalytic reactions. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>цитохром P450</kwd><kwd>биоэлектрохимия</kwd><kwd>рибофлавин</kwd><kwd>электрокатализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cytochrome P450</kwd><kwd>bioelectrochemistry</kwd><kwd>riboflavin</kwd><kwd>electrocatalysis</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">Кузиков А.В., Булко Т.В., Королева П.И., Масамрех Р.А., Бабкина С.С., Гилеп А.А., Шумянцева В.В.
