Glycation of proteins, nucleotides and basic phospholipids by glyoxal and methylglyoxal--physiological substrates of glyoxalase 1--is potentially damaging to the proteome, genome and lipidome. Glyoxalase 1 suppresses glycation by these alpha-oxoaldehyde metabolites and thereby represents part of the enzymatic defence against glycation. Albert Szent-Györgyi pioneered and struggled to understand the physiological function of methylglyoxal and the glyoxalase system. We now appreciate that glyoxalase 1 protects against dicarbonyl modifications of the proteome, genome and lipome. Latest research suggests there are functional modifications of this process--implying a role in cell signalling, ageing and disease.
乙二醛和甲基乙二醛(乙二醛酶1的生理底物)对蛋白质、核苷酸和碱性磷脂的糖基化作用可能会对蛋白质组、基因组和脂质组造成损害。乙二醛酶1可抑制这些α-氧代醛代谢物引起的糖基化作用,因此是对抗糖基化的酶防御机制的一部分。阿尔伯特·圣捷尔吉率先并努力理解甲基乙二醛和乙二醛酶系统的生理功能。我们现在认识到,乙二醛酶1可防止蛋白质组、基因组和脂质组发生二羰基修饰。最新研究表明,这一过程存在功能修饰,意味着其在细胞信号传导、衰老和疾病中发挥作用。
