乙酰化、能量代谢与肉品品质的关联

Association of Meat Quality with Acetylation and Energy Metabolism

蛋白质翻译后修饰对生命的调控极其重要。赖氨酸乙酰化是一种普遍存在于生命当中、动态可逆的蛋白质翻译后修饰方式,调控众多能量代谢过程。能量代谢的调控对宰后肉品品质的形成起着关键作用。在肌肉体系当中,异常的能量代谢进程会导致异质肉的发生。本文首先阐述能量代谢对宰后肉品品质的影响,之后总结乙酰化对能量代谢的调控作用,进而引出乙酰化对肉品品质的影响,论述乙酰化调控肉品品质潜在的宰后生理因素。最后,对乙酰化在肉品科学领域的发展进行展望,并总结得出乙酰化通过调控能量代谢相关蛋白影响能量代谢进程,最终改变肉品品质。

Protein post-translational modifications are of great importance for the regulation of life. Lysine acetylation is a dynamic and reversible protein post-translational modi fication, which is universal in life and regulates many energy metabolism processes. The regulation of energy metabolism plays a key role in the formation of meat quality. In the muscle system, abnormal energy metabolism can lead to the occurrence of heterogeneous meat. In this context, this paper first demonstrates the effect of energy metabolism on meat quality after slaughter, and then discusses the regulatory effect of acetylation on energy metabolism and consequently on meat quality, as well as the underlying physiological factors. Finally, we give some perspectives on the future of acetylation in meat science, and we conclude that acetylation affects energy metabolism by regulating the proteins related to it, and ultimately changes meat quality.
