The discovery of prolyl hydroxylase domain proteins (PHDs) as key enzymes in the hypoxia inducible factor (HIF) pathway has been followed by reports of a multitude of non-HIF substrates of PHD. Reporting in eLife, Cockman et al. (2019) find a surprising lack of detectable PHD activity toward any of them.
脯氨酰羟化酶结构域蛋白 (PHD) 的发现作为缺氧诱导因子 (HIF) 通路中的关键酶,随后有报道称 PHD 有多种非 HIF 底物。Cockman 等人在《eLife》杂志上报道(2019 年)发现,它们中没有任何一种可被检测到的 PHD 活性。
