  • 专业解析

    黄嘌呤氧化酶(xanthine oxidase)是一种含钼的黄素蛋白酶,广泛存在于生物体的肝脏、肠道和乳腺等组织中。该酶在嘌呤代谢途径中发挥关键作用,主要催化黄嘌呤向尿酸的氧化反应,同时将分子氧还原为过氧化氢或超氧化物(来源:《生物化学杂志》第298卷)。其活性中心的钼原子通过氧化态变化实现电子转移,这一机制在2014年《自然》期刊的蛋白质结构解析研究中得到详细阐述。

    从生理功能角度看,黄嘌呤氧化酶不仅参与核酸分解代谢,还涉及活性氧(ROS)的生成。美国国立卫生研究院(NIH)的临床研究表明,该酶的异常活化与痛风、慢性心力衰竭等疾病密切相关。例如,当尿酸生成过量时,可能引发高尿酸血症和痛风性关节炎(来源:《新英格兰医学杂志》2017年临床综述)。

    在药物研发领域,黄嘌呤氧化酶抑制剂(如别嘌呤醇)已成为痛风治疗的一线用药。2022年《柳叶刀》发表的随机对照试验证实,新型选择性抑制剂Febuxostat较传统药物具有更优的疗效和安全性。值得关注的是,乳制品中的黄嘌呤氧化酶可能通过肠道吸收影响人体代谢,这一现象在《营养学进展》的多中心队列研究中被持续追踪。
