ENTRY       EC 2.5.1.1
NAME        Dimethylallyltranstransferase
            Geranyl-diphosphate synthase
            Prenyltransferase
            Dimethylallyltransferase
CLASS       Transferases
            Transferring alkyl or aryl groups, other than methyl groups
SYSNAME     Dimethylallyl-diphosphate:isopentenyl-diphosphate
            dimethylallyltranstransferase
REACTION    Dimethylallyl diphosphate + Isopentenyl diphosphate =
            Pyrophosphate + Geranyl diphosphate
SUBSTRATE   Dimethylallyl diphosphate
            Isopentenyl diphosphate
PRODUCT     Pyrophosphate
            Geranyl diphosphate
COMMENT     This enzyme will not accept larger prenyl diphosphates as
            efficient donors.
