ENTRY       EC 2.5.1.30
NAME        trans-Hexaprenyltranstransferase
            all-trans-Heptaprenyl-diphosphate synthase
CLASS       Transferases
            Transferring alkyl or aryl groups, other than methyl groups
SYSNAME     all-trans-Hexaprenyl-diphosphate:isopentenyl-diphosphate
            $ hexaprenyltranstransferase
REACTION    all-trans-Hexaprenyl diphosphate + Isopentenyl diphosphate =
            Pyrophosphate + all-trans-Heptaprenyl diphosphate
SUBSTRATE   all-trans-Hexaprenyl diphosphate
            Isopentenyl diphosphate
PRODUCT     Pyrophosphate
            all-trans-Heptaprenyl diphosphate
COMMENT     This enzyme will also use trans,trans-farnesyl diphosphate and
            all-trans-prenyl diphosphates of intermediate size as donors, but
            not dimethylallyl diphosphate.
