The changes in the protein fractions were analyzed by one-dimensional and two- dimensional electrophoresis with the following identification by mass-spectrometric methods. The changes in muscle proteins in the course of autolytic processes were found. For example, the intensity of the protein spots of pyruvate kinase, myosin light chains and adenylate kinase increased during autolysis. The fragments of myosin light chains appeared. The activity of the endogenous enzymes, such as calpain 3 and cathepsin D in the course autolysis was also studied. During the first 24 hours after animal slaughter, the activity of these enzymes reached the maximum level and then decreased. The results of the performed investigations confirmed that pork and beef have different rate of autolysis but similar proteomic changes.</p></abstract><trans-abstract xml:lang="ru"><p>В работе представлены исследования по изучению автолитических превращений в мышцах свинины и говядины протеомными методами. Изменения белковых фракций анализировали одномерным и двумерным электрофорезом с дальнейшей идентификацией масс-спектрометрическими методами, были обнаружены изменения в мышечных белках, с течением автолитических процессов. Так, интенсивность белковых пятен пируваткиназы, легких цепей миозина и аденилаткиназы увеличивалась в процессе автолиза. Отмечается появление фрагментов легких цепей миозина. Также была изучена активность эндогенных ферментов, таких как кальпаин 3 и катепсин D в ходе автолиза. В первые 24 часа после убоя животного активность данных ферментов достигала максимального значения, затем снижалась. Результаты проведенных исследований подтвердили, что у свинины и говядины различная скорость протекания автолиза, но сходные протеомные изменения.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>автолиз</kwd><kwd>свинина</kwd><kwd>говядина</kwd><kwd>протеомика</kwd><kwd>электрофорез</kwd><kwd>белок</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autolysis</kwd><kwd>pork</kwd><kwd>beef</kwd><kwd>proteomics</kwd><kwd>electrophoresis</kwd><kwd>protein</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">Chernukha, I.M., Fedulova, L.V., Akhremko, A.G., Kotenkova, E.A.
