(A) Mass spectra for the control (inset) and 6-cyano-2′-deoxy-2′-fluoro-UMP (35) treated ODCases. (B) The biochemical transformation of 6-cyano- and 6-cyano-2′-deoxy-2′-fluoro-UMP derivatives by ODCase. In the former case, a hydrolytic process was observed, while in the latter case a covalent complex was observed in the active site of ODCase.
