Comments [?]

case <OC:Gammaproteobacteria>
FUNCTIONCatalyzes the sequential condensation of isopentenyl diphosphate (IPP) with (2E,6E)-farnesyl diphosphate (E,E-FPP) to yield (2Z,6Z,10Z,14Z,18Z,22Z,26Z,30Z,34E,38E)-undecaprenyl diphosphate (di- trans,octa-cis-UPP). UPP is the precursor of glycosyl carrier lipid in the biosynthesis of bacterial cell wall polysaccharide components such as peptidoglycan and lipopolysaccharide.
CATALYTIC ACTIVITY Reaction=(2E,6E)-farnesyl diphosphate + 8 isopentenyl diphosphate = di- trans,octa-cis-undecaprenyl diphosphate + 8 diphosphate; Xref=Rhea:RHEA:27551, ChEBI:CHEBI:33019, ChEBI:CHEBI:58405, ChEBI:CHEBI:128769, ChEBI:CHEBI:175763; EC=2.5.1.31;
else case <OC:Archaea>
FUNCTIONCatalyzes the sequential condensation of isopentenyl diphosphate (IPP) with geranylgeranyl diphosphate (GGPP) to yield (2Z,6Z,10Z,14Z,18Z,22Z,26Z,30E,34E,38E)-undecaprenyl diphosphate (tritrans,heptacis-UPP). It is probably the precursor of glycosyl carrier lipids.
CATALYTIC ACTIVITY Reaction=geranylgeranyl diphosphate + 7 isopentenyl diphosphate = 7 diphosphate + tri-trans,hepta-cis-undecaprenyl diphosphate; Xref=Rhea:RHEA:27622, ChEBI:CHEBI:33019, ChEBI:CHEBI:57533, ChEBI:CHEBI:60388, ChEBI:CHEBI:128769; EC=2.5.1.89;

Comments Actinomycetota possess different types of isoprenyl transferases (decaprenyl diphosphate synthase; trans,polycis-decaprenyl diphosphate synthase; (2Z,6E)-farnesyl diphosphate synthase; trans,polycis-polyprenyl diphosphate synthase) which are all homologous to ISPT in primary sequence (and match the family MF_01139) but with a different substrate specificity (isoprenyl acceptor) and chain-length determination due to a few residues.
