2.1.1.45
A17T/D116A/D254E
the mutant shows decreased sensitivity towards 5-fluorodeoxyuridine compared to the wild type enzyme
703950
2.1.1.45
A191K
inactive. Mutant has large areas of hydrophobic region exposed to solvent and exposes the hydrophobic beta-sheets in the dimer interface
757176
2.1.1.45
A191K
the mutant enzyme displays a kcat value of 6fold lower than wild type
706625
2.1.1.45
A191K
the mutant exhibits about 25% of the catalytic activity of the wild type enzyme. The mutant exhibits nonhyperbolic behavior with respect to dUMP and inhibition of catalysis is reversed by substrate saturation
