1 Type I IPP isomerase (IDI-1) utilizes a divalent metal in a protonation-deprotonation reaction; whereas, the type II enzyme (IDI-2) requires reduced flavin. 4,6-dinitro-o-cresol isopentenyl-diphosphate delta isomerase 2 Homo sapiens
2 These studies indicate that the irreversible inhibitors inactivate the reduced flavin required for catalysis by electrophilic alkylation and are consistent with a protonation-deprotonation mechanism for the isomerization catalyzed by IDI-2. 4,6-dinitro-o-cresol isopentenyl-diphosphate delta isomerase 2 Homo sapiens
