aldo/keto reductase (KRED) enzymes, which allow the highly sensitive and reliable determination of activity and kinetic constants of known and unknown enzymes, as well as an immediate enantioselectivity typing. Because of its simplicity in microtiter plate format, the assay qualifies for the discovery of novel KREDs of yet unknown specificity among this vast enzyme superfamily. The suitability of this approach
对映体纯的1-(6-甲氧基萘-2-基)和1-(6-(二甲氨基)萘-2-基)甲醇是醛基/酮还原酶(KRED)酶的荧光底物,可以高度灵敏和可靠地进行测定已知和未知酶的活性和动力学常数,以及立即的对映选择性分型。由于其微量滴定板形式的简单性,该测定符合在这个庞大的酶超家族中发现特异性未知的新型KRED的资格。通过从宏基因组学方法排列的大量短链脱氢酶/还原酶(SDR)酶的示例性筛选,说明了该方法对酶分型的适用性。
