Function
[PCRB_BACSU] Prenyltransferase that catalyzes in vivo the transfer of the heptaprenyl moiety of heptaprenyl pyrophosphate (HepPP; 35 carbon atoms) to the C3 hydroxyl of sn-glycerol-1-phosphate (G1P), producing heptaprenylglyceryl phosphate (HepGP). This reaction is an ether-bond-formation step in the biosynthesis of archaea-type G1P-based membrane lipids found in Bacillales. To a much lesser extent, is also able to use geranyl diphosphate (GPP; C10) and geranylgeranyl diphosphate (GGPP; C20) as the prenyl donors, but not farnesyl pyrophosphate (FPP; C15). Can not use glycerol-3-phosphate (G3P) or 3-phosphoglycerate (3PG) as an acceptor.[1] [2] [3]
Publication Abstract from PubMed
Well structured: As a new triose phosphate isomerase (TIM) barrel-fold prenyl transferase, PcrB catalyzes the production of heptaprenylglyceryl phosphate from heptaprenyl diphosphate and glycerol-1-phosphate. Crystal structures of PcrB from Bacillus subtilis and Staphylococcus aureus in complex with ligands were solved, and together with site-directed mutagenesis and bioinformatics analyses, clearly reveal the catalytic mechanism of the enzyme.
