Molecular Mechanism of Thymidylate Synthase Inhibition by N-Hydroxy-dCMP in View of Spectrophotometric and Crystallographic Studies.

Int J Mol Sci 2021 Apr 30;22(9). Epub 2021 Apr 30.

Nencki Institute of Experimental Biology, Polish Academy of Sciences, 3 Pasteur St., PL-02-093 Warszawa, Poland.

Novel evidence is presented allowing further clarification of the mechanism of the slow-binding thymidylate synthase (TS) inhibition by N-hydroxy-dCMP (N-OH-dCMP). Spectrophotometric monitoring documented time- and temperature-, and N-OH-dCMP-dependent TS-catalyzed dihydrofolate production, accompanying the mouse enzyme incubation with N-OH-dCMP and N-methylenetetrahydrofolate, known to inactivate the enzyme by the covalent binding of the inhibitor, suggesting the demonstrated reaction to be uncoupled from the pyrimidine C(5) methylation. The latter was in accord with the hypothesis based on the previously presented structure of mouse TS (cf. Read More
