dTTP
inhibition of deamination reaction
dTTP
inhibits by increasing the kcat several fold, mutants S111T and E138D are less sensitive to dTTP, overview
dTTP
inhibits the enzyme in a nonallosterical way, cooperative kinetics are imposed by a dTTP-dependent lag of product formation observed in presteady-state kinetics, the lag may be derived from a slow equilibration between an inactive and an active conformation of dCTP deaminase represented by the dTTP complex and the dUTP/dCTP complex, respectively, steady-state kinetic analysis of dTTP inhibition, overview
dTTP
the inhibitor has a regukatory function for the bifunctional enzyme, mechanism of regulation by conformational changes, overview
