The investigation of a difluoromethyl-bearing nucleoside with the fluorinase enzyme is described. 5′,5′-Difluoro-5′-deoxyadenosine7(F2DA) was synthesised from adenosine, and found to bind to the fluorinase enzyme by isothermal titration calorimetry with similar affinity compared to 5′-fluoro-5′-deoxyadenosine2(FDA), the natural product of the enzymatic reaction. F2DA7was found, however, not to undergo the enzyme catalysed reaction withl-selenomethionine, unlike FDA2, which undergoes reaction withl-selenomethionine to generateSe-adenosylselenomethionine. A co-crystal structure of the fluorinase and F2DA7and tartrate was solved to 1.8 Å, and revealed that the difluoromethyl group bridges interactions known to be essential for activation of the single fluorine in FDA2. An unusual hydrogen bonding interaction between the hydrogen of the difluoromethyl group and one of the hydroxyl oxygens of the tartrate ligand was also observed. The bridging interactions, coupled with the inherently stronger C–F bond in the difluoromethyl group, offers an explanation for why no reaction is observed.
