Comprehensive study of protein phosphorylation， acetylation， ubiquitination and S-nitrosylation profiles in pre- and post-rigor meat

引用

Food Science and Human Wellness 2024年

作者： Chi Ren Yuqiang Bai Yejun Zhang Chengli Hou Li Chen james d.Morton Xin Li Zhenyu Wang dequan Zhang Institute of Food Science and Technology， Chinese Academy of Agricultural Sciences/Key Laboratory of Agro-products Quality & Safety in Harvest， Storage， Transportation， Management and Control， Ministry of Agriculture and Rural Affairs Faculty of Agriculture and Life Sciences， Lincoln University Lincoln 7647， New Zealand

This study investigated the integrated atlas of protein phosphorylation， acetylation， ubiquitination and S-nitrosylation in pre-rigor (0.5 h) and post-rigor (5 d) lamb to interpret the roles of protein post-translational modifications (PTMs) during meat aging. The results showed that the most common PTMs in postmortem meat were phosphorylated proteins. PTMs regulation during the postmortem period altered proteins involved in metabolic pathways and muscle contraction. The phosphorylation and ubiquitination of proteins located in mitochondria and nuclear changed significantly between 0.5 h and 5 d postmortem. Gene set enrichment analysis (GSEA) revealed possible roles of total PTMs proteins， with a general downregulation of phosphorylation， acetylation and ubiquitination. There was a weak correlation in the lysine PTM of acetylation and ubiquitination at the same site in postmortem meat. Multiple PTMs of proteins in glycolysis， TCA cycle， muscle contraction and the calcium signaling pathway cooperatively regulate meat quality development from pre-rigor to post-rigor.
