The revealed protein substances have different origin: structural proteins (fragments of troponins T and myosin light chains), and metabolic proteins (creatine kinase, pyruvate kinase and alpha-enolase). The decomposition of the fractions of fast skeletal muscle troponin T in 28.0 kDa, 27 kDa and 26.5 kDa was most pronounced.</p><p>Identification of constitutive proteins and detection of the products of post — mortem degradation of protein molecules make them suitable candidates for meat quality markers and the following study of these specific fragments will lead to better understanding of the proteolytic activities that take part in the post mortem muscle transformation into meat.</p></abstract><trans-abstract xml:lang="ru"><p>При помощи электрофоретических методов с дальнейшей масс-спектрометрической идентификацией было обнаружено 8 белковых веществ, претерпевающие изменения в ходе автолиза. Выявленные белковые вещества имеют различное происхождение: структурные белки (фрагменты тропонинов Т и легкие цепи миозина), а также метаболические белки (креатинкиназа, пируваткиназа и альфаенолаза). Наиболее выраженно проходила декомпозиция фракций тропонина Т быстрых скелетных мышц в 28,0 кДа, 27 кДа и 26,5 кДа.</p><p>Идентификация конститутивных белков и  выявление продуктов посмертной деградации белковых молекул, делают их хорошими кандидатами маркеров качества мяса, а дальнейшие исследования этих конкретных фрагментов приведут к лучшему пониманию протеолитических активностей, участвующих в посмертном превращении мышц в мясо.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>автолиз</kwd><kwd>свинина</kwd><kwd>протеомика</kwd><kwd>мышечный белок</kwd><kwd>двумерный электрофорез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autolysis</kwd><kwd>pork</kwd><kwd>proteomics</kwd><kwd>muscle protein</kwd><kwd>two-dimensional electrophoresis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">грант Российского научного фонда (проект № 16–16–10073).</funding-statement><funding-statement xml:lang="en">The study was funded by the grant of the Russian Scientific Foundation (Project No. 16–16–10073).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">ExPASy.
