Name
hexaprenyl diphosphate synthase [(2E,6E)-farnesyl-diphosphate specific];
HexPS (ambiguous);
hexaprenyl pyrophosphate synthetase (ambiguous);
hexaprenyl diphosphate synthase (ambiguous)
Class
Transferases;
Transferring alkyl or aryl groups, other than methyl groups;
Transferring alkyl or aryl groups, other than methyl groups (only sub-subclass identified to date)
BRITE hierarchy
Sysname
(2E,6E)-farnesyl-diphosphate:isopentenyl-diphosphate farnesyltranstransferase (adding 3 isopentenyl units)
Reaction(IUBMB)
(2E,6E)-farnesyl diphosphate + 3 isopentenyl diphosphate = 3 diphosphate + all-trans-hexaprenyl diphosphate [RN:R09245]
Reaction(KEGG)
Substrate
(2E,6E)-farnesyl diphosphate [CPD:C00448];
isopentenyl diphosphate [CPD:C00129]
Product
diphosphate [CPD:C00013];
all-trans-hexaprenyl diphosphate [CPD:C01230]
Comment
The enzyme prefers farnesyl diphosphate to geranylgeranyl diphosphate as an allylic substrate and does not show activity for geranyl diphosphate and dimethylallyl diphosphate [1].
