Abstract
The spore coat protein CotA from Bacillus subtilis was previously identified as a laccase. We have now found that CotA also shows strong bilirubin oxidase activity and markedly higher affinity for bilirubin than conventional bilirubin oxidase. This is the first characterization of bilirubin oxidase activity in a bacterial protein.
摘要
来自枯草芽孢杆菌的芽孢衣蛋白CotA先前被鉴定为一种漆酶。我们现在发现，CotA还表现出很强的胆红素氧化酶活性，并且与传统的胆红素氧化酶相比，对胆红素的亲和力明显更高。这是对细菌蛋白中胆红素氧化酶活性的首次表征。
