DE   chrysanthemyl diphosphate synthase.
AN   CPPase.
CA   2 dimethylallyl diphosphate = (R,R)-chrysanthemyl diphosphate +
CA   diphosphate.
CC   -!- Chrysanthemyl diphosphate is a monoterpene with a non-head-to-tail
CC       linkage; it is unlike most monoterpenoids, which are derived from
CC       geranyl diphosphate and have isoprene units that are linked head-
CC       to-tail.
CC   -!- The mechanism of its formation is similar to that of the early steps
CC       of squalene and phytoene biosynthesis.
CC   -!- Chrysanthemyl diphosphate is the precursor of chrysanthemic acid,
CC       the acid half of the pyrethroid insecticides found in chrysanthemums.
