<p>A novel isopentenyl pyrophosphate isomerase; and a gene coding for the same. An enzyme protein having the following physicochemical properties and having an isopentenyl pyrophosphate isomerase activity is provided. Function: It isomerizes isopentenyl pyrophosphate (IPP) to yield dimethylallyl pyrophosphate (DMAPP). It isomerizes DMAPP to yield IPP. Substrate specificity: It acts on isopentenyl pyrophosphate (IPP) as a substrate. It acts also on DMAPP as a substrate. Reaction conditions: A divalent metal ion, FMN, and NADPH are essential to the isopentenyl pyrophosphate (IPP) isomerase activity.</p> |
