The polyprenyl diphosphate synthase consists of a tetramer comprising two units of decaprenyl-diphosphate synthase subunit 1 (PDSS1) and two units of decaprenyl-diphosphate synthase subunit 2 (PDSS2). It catalyses the combination of 2-trans,6-trans-farnesyl diphosphate (FPP) with isopentenyl diphosphate (IPPP) to form the polyisoprenoid tail all-trans-decaprenyl diphosphate (all-E-10PrP2) (Saiki et al. 2005, Tekle et al. 2008).
