Abstract:
... Isopentenyl diphosphate isomerase (IDI, EC 5.3.3.2) catalyzes the revisable conversion of 5-carbon isopentenyl diphosphate and its isomer dimethylallyl diphosphate, which are the essential precursors for isoprenoids, including carotenoids. Here we report on the cloning and characterization of a novel cDNA encoding IDI from sweet potato. The full-length cDNA is 1155 bp with an ORF of 892 bp encodin ...
