基于蛋白质组学分析蛋白酶体对宰后秦川牛肉贮藏期间品质变化的影响

摘要/Abstract

摘要： 摘要：本研究以宰后4 ℃条件下不同贮藏期的秦川牛背最长肌为研究对象，测定品质指标、能量水平、蛋白酶体活性变化，鉴定与蛋白酶体相关的差异蛋白质（Differential expression proteins，DEPs），利用生物信息学方法分析蛋白酶体对宰后牛肉品质及能量代谢的响应机制，结果如下：随贮藏时间的延长，pH值呈先降低后升高趋势；b*值和MFI呈上升趋势；L*值、a*值、离心损失、蒸煮损失、剪切力呈先上升后下降趋势；能量基本物质 ATP、ADP、AMP含量呈下降趋势；20S蛋白酶体活性显著降低（P < 0.05）；相关性分析结果显示：20S蛋白酶体活性与b*呈显著负相关（P < 0.05），与ADP含量呈显著正相关（P < 0.05），与AMP含量呈极显著正相关（P < 0.01），与MFI呈极显著负相关（P < 0.01），表明蛋白酶体活性与能量代谢及品质间存在密切联系。结合4D-LFQ蛋白质组学技术，鉴定出8种差异表达的蛋白酶体亚基，及27种相关DEPs；GO分析和KEGG Pathway分析发现，这些蛋白酶体亚基及其相关的DEPs具有内肽酶活性、肌动蛋白结合、微丝运动活性等分子功能，参与泛素依赖性蛋白质分解代谢、骨骼肌收缩、肌肉收缩、糖酵解等生物过程，引起秦川牛肉品质变化；宰后初期蛋白酶体通过消耗能量物质分解代谢蛋白调控生物途径，后期能量物质耗尽，蛋白酶体可通过糖酵解提供的能量以及非ATP依赖型蛋白酶体亚基，实现对宰后蛋白质的分解代谢，最终影响秦川牛肉的品质。

Abstract: Abstract：In this study, the longissimus dorsi muscle of Qinchuan cattle stored at 4 ℃ after slaughter was used as the object of study to determine quality indicators, energy levels and proteasome activity, and to identify DEPs associated with the proteasome. The results were as follows: pH decreased and then increased with increasing storage time; b* and MFI increased; L*, a*, centrifugal loss, cooking loss and shear force increased and then decreased; ATP, ADP and AMP the basic energy substances, decreased; 20S proteasome activity decreased significantly (P < 0.05); The correlation analysis showed that the 20S proteasome activity was significantly negatively correlated with b* (P < 0.05), with ADP content (P < 0.05), with AMP content (P < 0.01), and with MFI (P < 0.01), indicating a close relationship between proteasome activity and energy metabolism and beef quality. Combined with 4D-LFQ proteomics technology, eight differentially expressed proteasome subunits, and 27 associated DEPs were identified; GO analysis and KEGG Pathway analysis revealed that these proteasome subunits and their associated DEPs have molecular functions such as endopeptidase activity, actin binding, microfilament motility activity, and are involved in ubiquitin-dependent proteolytic metabolism, skeletal muscle contraction, In the early postmortem period, the proteasome regulated the biological pathway by consuming energetic material to catabolize proteins, and in the later period, when the energetic material was depleted, the proteasome could realize the catabolism of postmortem proteins through the energy provided by glycolysis and non-ATP-dependent proteasome subunits, which eventually affected the quality of Qinchuan beef.
