Bacterial isoprenoid synthesis - the Rohmer pathway Current biosynthetic evidence indicates that the steps from IPP to isoprenoids in Eubacteria are the same as those in eukaryotes [62-69] (see [70-73] for literature). Especially the incorporation of C-labeled precursors into prokaryotic hopanoids, sterol surrogates in bacterial membranes (see [73] and literature cited therein), or into ubiquinone-8 [70] has revealed that the classic pathway of IPP formation starting from acetyl-CoA via acetoacetyl-CoA, HMG-CoA, MVA, MVA-P, and MVA-PP does not exist in a great variety of bacteria, including E. coli Zymomonas mobilis, Methylobacterium organophilum, Rhodopseudomonas palustris, R. acidophila, Acetobacter aceti ssp. xylinum, but also in the thylakoids of the cyanobacterium Synechocystis sp. [74].
