Witryna1 paź 2001 · IMPDH (EC 1.1.1.205) catalyzes the NAD-dependent oxidation of inosine 5′-monophosphate (IMP) to xanthosine 5′-monophosphate (XMP).The enzyme follows an ordered Bi-Bi reaction sequence of substrate and cofactor binding and product release. In the first step, IMP binds to IMPDH, followed by the binding of the cofactor NAD. WitrynaIn mycophenolate-treated patients, IMPDH activity was a significantly better predictor of response than mycophenolate dose (AUC 0.84 vs. 0.62, p < 0.001). Immunosuppression strongly affects vaccine response. Modifications to immunosuppression should be considered in order to facilitate this response.

Witryna1 gru 2024 · The immunosuppressant MPA was shown to trap a covalent intermediate of the IMPDH enzyme reaction, making it an uncompetitive inhibitor with respect to both IMP and NAD + (Hedstrom, 2009). Ribavirin, on the other hand, is converted to ribavirin-5′-monophosphate, which binds to the IMP site of IMPDH (Shu and Nair, 2008).
