Tuning the production of variable length, fluorescent polyisoprenoids using surfactant-controlled enzymatic synthesis.

ABSTRACT: Bactoprenyl diphosphate (BPP), a two-E eight-Z configuration C55 isoprenoid, serves as a critical anchor for the biosynthesis of complex glycans central to bacterial survival and pathogenesis. BPP is formed by the polymerase undecaprenyl pyrophosphate synthase (UppS), which catalyzes the elongation of a single farnesyl diphosphate (FPP) with eight Z-configuration isoprene units from eight isopentenyl diphosphates. In vitro analysis of UppS and other polyprenyl diphosphate synthases requires the addition of a surfactant such as Triton X-100 to stimulate the release of the hydrophobic product from the enzyme for effective and efficient turnover. Here using a fluorescent 2-nitrileanilinogeranyl diphosphate analogue of FPP, we have found that a wide range of surfactants can stimulate release o
