A farnesyl diphosphate (FPP) phosphatase. Involved in biofilm formation, its disruption blocks biofilm synthesis which is restored by exogenous farnesol (PubMed:25308276). Releases diphosphate from FPP, was initally suggested to be a squalene synthase. Diphosphate release is higher from FPP than geranyl pyrophosphate (GPP) or geranylgeranyl pyrophosphate (GGPP). Biofilm synthesis is partially restored by exogenous squalene, beta-carotene or retinol. Required for integrity of cell membrane lipid rafts (PubMed:20713508). Involved in spatial organization of membranes, required for the flotillin-like proteins FloT and FloA to function correctly (PubMed:23651456). (2E,6E)-farnesyl diphosphate + H2O = (2E,6E)-farnesol + diphosphate Diphosphate release from FPP is inhibited by zaragozic acid. Monomer. Loss of biofilm formation (PubMed:20713508, PubMed:25308276). Loss of a dark-orange pigment from cells, alteration of cellular lipid profile. Significant reduction of proteins found in detergent-resistant membrane (DRM) fractions (PubMed:20713508). Decrease in membrane fluidity, about 30% decrease in protein secretion (PubMed:23651456). Belongs to the phytoene/squalene synthase family. Was originally thought to be a squalene synthase (PubMed:20713508). Further characterization suggests it is actually a farnesyl diphosphate phosphatase (PubMed:25308276). Extended N-terminus.
