Phosphorothioate analogues of phosphoribosyldiphosphate are substrates of quinolinate phosphoribosyltransferase.
Phosphorothioate analogues of phosphoribosyldiphosphate (P-Rib-PP) can act as substrates of quinolinate phosphoribosyltransferase. The order of effectiveness as substrates, with Mg2+ as the activating metal ion, was P-Rib-PP greater than P-Rib-PPbeta S greater than P-Rib-PP alpha S(Sp) greater than P-Rib-PP alsph S(Rp). Cd2+ was more effective than Mg2+ with the Rp diastereommer.
