| 5.3.3.2 | Isopentenyl diphosphate = dimethylallyl diphosphate |
catalytic mechanism in which a cysteine initiates the reaction by protonating the carbon-carbon double bond, with the antarafacial rearrangement ultimately achieved by one of the glutamates involved in the metal coordination sphere |
650979 |
| 5.3.3.2 | Isopentenyl diphosphate = dimethylallyl diphosphate |
in the rate determining step, the C2-H bond of isopentenyl diphosphate is cleaved. General acid/base catalysis may be involved during turnover |
690929 |
| 5.3.3.2 | Isopentenyl diphosphate = dimethylallyl diphosphate |
interconversion of substrate is catalyzed by a stereoselective antarafacial [1.3] transposition of a proton involving residues C87, E149, W197 and Y137 |
681413 |
| 5.3.3.2 | Isopentenyl diphosphate = dimethylallyl diphosphate |
reaction involves protonation and deprotonation of the isoprenoid unit and proceeds through a carbocationic transition state. Glu116/Tyr104 and Cys67 are involved in the antarafacial addition/elimination of protons during isomerization |
652367 |
| 5.3.3.2 | Isopentenyl diphosphate = dimethylallyl diphosphate |
the mechanism of isomerizaion reaction involves protonation of the unactivated carbon-carbon double bond in the substrate, Glu116 is involved in the protonation step and Cys67 is involved in the elimination step |
