The fluorinase enzyme from Streptomyces cattleya is shown to catalyse a direct displacement of bromide and iodide by fluoride ion from 5'-bromodeoxyadenosine (5'-BrDA) and 5'-iododeoxyadenosine (5'-IDA) respectively to form 5'-fluorodeoxyadenosine (5'-FDA) in the absence of l-methionine (l-Met) or S-adenosyl-l-methionine (SAM). 5'-BrDA is the most efficient substrate for this enzyme catalysed Finkelstein reaction.
链霉菌属卡特利链霉菌的氟化物酶被证明能够催化 5'-溴脱氧腺苷（5'-BrDA）和 5'-碘脱氧腺苷（5'-IDA）分别将溴离子和碘离子直接取代为氟离子，从而在没有 l-蛋氨酸（l-Met）或 S-腺苷-l-蛋氨酸（SAM）的情况下形成 5'-氟脱氧腺苷（5'-FDA）。对于该酶催化的 Finkelstein 反应，5'-BrDA 是最有效的底物。
