CBR3（carbonyl reductase 3），癌症关联基因，基因ID：874，羰基还原酶3催化大量生物和药理活性羰基化合物还原为相应的醇。酶被分类为单体NADPH依赖的氧化还原酶。CBR3包含三个外显子，跨越11.2千碱基，与另一个羰基还原酶基因CBR1紧密相连。[由RefSeq提供，2008年7月]Carbonyl reductase 3 catalyzes the reduction of a large number of biologically and pharmacologically active carbonyl compounds to their corresponding alcohols. The enzyme is classified as a monomeric NADPH-dependent oxidoreductase. CBR3 contains three exons spanning 11.2 kilobases and is closely linked to another carbonyl reductase gene - CBR1.
