一般描述
Formerly E.C.1.1.3.22
应用
来自牛奶的黄嘌呤氧化酶已被用作生成超氧化物的来源。它也已用作内部校准电化学连续酶测定（internally calibrated electrochemical continuous enzyme assay，ICECEA）中的模型酶。
生化/生理作用
异黄酮染料木素在0.1-4.0 μM的浓度范围内显示出对黄嘌呤氧化酶的抑制，高于5 μM的浓度则会激活黄嘌呤氧化酶。
木糖氧化酶是一种含钼酶，存在于细胞质中，能够被黄酮类化合物有效抑制。它在一些药物和嘌呤嘧啶代谢中有重要作用。它被认为是活性氧簇的生物来源。
黄嘌呤氧化酶可用作氧化应激的潜在生物标记。它还涉及组织和血管损伤，例如肝损伤、炎症性疾病和慢性心力衰竭。
单位定义
在pH7.5,25℃条件下，一个单位可每分钟将1.0 μmole黄嘌呤转化为尿酸。以次黄嘌呤为底物可获得约50％的活性。
外形
含有0.5％的水杨酸钠。

Generally, enzyme immobilization on nanoparticles leads to nano-conjugates presenting partially preserved, or even absent, biological properties. Notwithstanding, recent research demonstrated that the coupling to nanomaterials can improve the activity of immobilized enzymes. Herein, xanthine oxidase (XO) was immobilized by self-assembly

Cells are exposed to several types of integrin stimuli, which generate responses generally referred to as "integrin signals", but the specific responses to different integrin stimuli are poorly defined. In this study, signals induced by integrin ligation during cell attachment
