Function

DPDS_MYCTU Catalyzes the sequential condensation of isopentenyl diphosphate (IPP) in the cis configuration with (2Z,6E)-farnesyl diphosphate (Z-FPP or EZ-FPP) generating the 50 carbon product trans,polycis-decaprenyl diphosphate. When (2E,6E)-farnesyl diphosphate (E-FPP or EE-FPP) is used in vitro, both primary products decaprenyl diphosphate and (2E,6E,10E)-geranylgeranyl diphosphate (EEE-GGPP) are synthesized. M.tuberculosis does not synthesize (2E,6E,10Z)-geranylgeranyl diphosphate (EEZ-GGPP) and heptaprenyl diphosphate. Can also accept many different allylic substrates, including E-geranyl diphosphate (E-GPP), neryl diphosphate (NPP), and all-trans-geranyl-geranyl diphosphate.^[1] ^[2] ^[3]

Publication Abstract from PubMed

In Mycobacterium tuberculosis, two related Z-prenyl diphosphate synthases, E,Z-farnesyl diphosphate synthase (Rv1086) and decaprenyl diphosphate synthase (Rv2361c), work in series to synthesize decaprenyl phosphate (C(50)) from isopentenyl diphosphate and E-geranyl diphosphate. Decaprenyl phosphate plays a central role in the biosynthesis of essential mycobacterial cell wall components, such as the mycolyl-arabinogalactan-peptidoglycan complex and lipoarabinomannan; thus, its synthesis has attracted considerable interest as a potential therapeutic target. Rv1086 is a unique prenyl diphosphate synthase in that it adds only one isoprene unit to geranyl diphosphate, generating the 15-carbon product (E,Z-farnesyl diphosphate). Rv2361c then adds a further seven isoprene units to E,Z-farnesyl diphosphate in a processive manner to generate the 50-carbon prenyl diphosphate, which is then dephosphorylated to generate a carrier for activated sugars. The molecular basis for chain-length discrimination by Rv1086 during synthesis is unknown. We also report the structure of apo Rv1086 with citronellyl diphosphate bound and with the product mimic E,E-farnesyl diphosphate bound. We report the structures of Rv2361c in the apo form, with isopentenyl diphosphate bound and with a substrate analogue, citronellyl diphosphate. The structures confirm the enzymes are very closely related. Detailed comparison reveals structural differences that account for chain-length control in Rv1086. We have tested this hypothesis and have identified a double mutant of Rv1086 that makes a range of longer lipid chains.
