    1.17.4.2 | 2',2'-difluoro-2'-deoxycytidine 5'-triphosphate |
complete inactivation of the enzyme by 1 equiv of 2',2'-difluoro-2'-deoxyCTP, F2CTP, in about 2 min proceeding via alkylation by the sugar of F2CTP and AdoCbl destruction. 0.47 equiv of a sugar moiety is covalently bound to RNR and 0.25 equiv of a cobalt(III) corrin is tightly associated, likely through a covalent interaction with C419 (Co-S) in the active site of RNR. Analysis of the relationship of the nonalkylative pathway for RNR inactivation relative to the alkylative pathway, overview |
