(all-E) hexaprenyl diphosphate synthase;
(all-trans) hexaprenyl diphosphate synthase;
hexaprenyl pyrophosphate synthase (ambiguous);
HexPPs (ambiguous);
hexaprenyl diphosphate synthase (ambiguous);
geranylgeranyl-diphosphate:isopentenyl-diphosphate transferase (adding 2 isopentenyl units)
Class

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
geranylgeranyl-diphosphate:3-methylbut-3-en-1-yl-diphosphate transferase (adding 2 units of 3-methylbut-3-en-1-yl)
Reaction(IUBMB)
geranylgeranyl diphosphate + 2 (3-methylbut-3-en-1-yl diphosphate) = 2 diphosphate + all-trans-hexaprenyl diphosphate [RN:
R09246 ]
Reaction(KEGG)
Substrate
geranylgeranyl diphosphate [CPD:
C00353 ];
3-methylbut-3-en-1-yl diphosphate [CPD:
C00129 ]
Product
diphosphate [CPD:
C00013 ];
all-trans-hexaprenyl diphosphate [CPD:
C01230 ]
Comment
The enzyme prefers geranylgeranyl diphosphate to farnesyl diphosphate as an allylic substrate and does not show activity for geranyl diphosphate and prenyl diphosphate. Requires Mg2+ [1].
