The first fluorogenic assay allowing for detection of microbial enzymes able to perform BaeyerâVilliger oxidation is described. This is based on the use of 4-oxopentyl umbelliferyl ether 1 as a fluorogenic substrate. When BaeyerâVilligerases active against this test ketone are present in the selected whole cells, 1 is transformed into 3-hydroxypropyl umbelliferyl ether 3, which, in a subsequent step, releases the fluorescent product umbelliferone. Different microorganisms, known to be endowed with BaeyerâVilligerase activity, were assayed.
描述了第一种荧光检测方法,用于检测能够进行Baeyer-Villiger氧化反应的微生物酶。这种方法基于使用4-氧戊基伞形花酯1作为荧光底物。当选定的全细胞中存在能够作用于此测试酮的Baeyer-Villiger酶时,1被转化为3-羟基丙基伞形花酯3,随后的步骤中释放出荧光产物伞形花内酯。对已知具有Baeyer-Villiger酶活性的不同微生物进行了检测。
