Abstract
Abstract
Undecaprenyl phosphate (UP) is essential for the biosynthesis of bacterial extracellular polysaccharides. UP is produced by the dephosphorylation of undecaprenyl diphosphate (UPP) via de novo synthetic and recycling pathways. Gram-positive bacteria contain remarkable amounts of undecaprenol (UOH), which is phosphorylated to UP, although UOH has not been found in Gram-negative bacteria. Here, current knowledge about UPP phosphatase and UOH kinase is reviewed. Dephosphorylation of UPP is catalyzed by a BacA homologue and a type-2 phosphatidic acid phosphatase (PAP2) homologue. The presence of one of these UPP phosphatases is essential for bacterial growth. The catalytic center of both types of enzyme is located outside the cytoplasmic membrane. In Gram-positive bacteria, an enzyme homologous to DgkA, which is the diacylglycerol kinase of Escherichia coli, catalyzes UOH phosphorylation. The possible role of UOH and the significance of systematic construction of Staphylococcus aureus mutants to determine UP metabolism are discussed.

Abstract
The bacterial cell wall is mainly composed of peptidoglycan, which is a three-dimensional network of long aminosugar strands located on the exterior of the cytoplasmic membrane. These strands consist of alternating MurNAc and GlcNAc units and are interlinked to each other via peptide moieties that are attached to the MurNAc residues. Peptidoglycan subunits are assembled on the cytoplasmic side of the bacterial membrane on a polyisoprenoid anchor and one of the key components in the synthesis of peptidoglycan is Lipid II. Being essential for bacterial cell survival, it forms an attractive target for antibacterial compounds such as vancomycin and several lantibiotics. Lipid II consists of one GlcNAc-MurNAc-pentapeptide subunit linked to a polyiosoprenoid anchor 11 subunits long via a pyrophosphate linker. This review focuses on this special molecule and addresses three questions. First, why are special lipid carriers as polyprenols used in the assembly of peptidoglycan? Secondly, how is Lipid II translocated across the bacterial cytoplasmic membrane? And finally, how is Lipid II used as a receptor for lantibiotics to kill bacteria?

Abstract
We analyzed a previously constructed stress-sensitive Streptococcus mutans mutant Tn-1 strain resulting from disruption by transposon Tn916 of a gene encoding a protein exhibiting amino acid sequence similarity to the Escherichia coli diacylglycerol kinase. It was confirmed that the mutation led to significantly reduced lipid kinase activity, while expression of the intact gene on a plasmid restored both kinase activity and the wild-type phenotype. Further analysis revealed that the product of the dgk gene in S. mutans predominantly recognizes a lipid substrate other than diacylglycerol, most likely undecaprenol, as demonstrated by its efficient phosphorylation and the resistance of the product of the reaction to saponification. The physiological role of the product of the dgk gene as a putative undecaprenol kinase was further supported by a significantly higher sensitivity of the mutant to bacitracin compared with that of the parental strain.

Abstract
Homologues of Escherichia coli bacA, encoding extremely hydrophobic proteins, were identified in the genomes of Staphylococcus aureus and Streptococcus pneumoniae. Allelic replacement mutagenesis demonstrated that the gene is not essential for in vitro growth in either organism, and the mutants showed no significant changes in growth rate or morphology. The Staph. aureus bacA mutant showed slightly reduced virulence in a mouse model of infection and an eightfold increase in bacitracin susceptibility. However, a Strep. pneumoniae bacA mutant was highly attenuated in a mouse model of infection, and demonstrated an increase in susceptibility to bacitracin of up to 160000-fold. These observations are consistent with the previously proposed role of BacA protein as undecaprenol kinase.

Abstract
Isopentenyl diphosphate (IPP), an important precursor of isoprenoid biosynthesis in prokaryotic and eukaryotic organisms, has been shown to activate Vgamma9/Vdelta2 T cells, the major subset of human gammadelta T cells. The biosynthesis of IPP has been first described as the acetate/mevalonate pathway. Recently, 1-deoxy-D-xylulose 5-phosphate (DOXP) and 2-C-methyl-D-erythritol 4-phosphate have been shown to be key metabolites in the DOXP pathway also leading to the formation of IPP in some eubacteria such as Escherichia coli. Here we report that the low molecular mass fraction of extracts from bacteria using the DOXP pathway induces Vgamma9/Vdelta2 T cell activation, while analogous preparations from bacteria using the classical mevalonate pathway fail to do so. Addition of 1-deoxy-D-xylulose potentiates the ability of E. coli extracts to activate Vgamma9/Vdelta2 T cells. As the amounts of IPP present in the bacterial preparations are not sufficient to induce significant Vgamma9/Vdelta2 T cell activation, our data suggest that compounds other than IPP associated with the DOXP pathway are responsible for Vgamma9/Vdelta2 T cell activation.

Abstract
Incorporation of 13C-labelled glucose, acetate, pyruvate or erythrose allowed the determination of the origin of the carbon atoms of triterpenoids of the hopane series and/or of the ubiquinones from several bacteria (Zymomonas mobilis, Methylobacterium fujisawaense, Escherichia coli and Alicyclobacillus acidoterrestris) confirmed our earlier results obtained by incorporation of 13C-labelled acetate into the hopanoids of other bacteria and led to the identification of a novel biosynthetic route for the early steps of isoprenoid biosynthesis. The C5 framework of isoprenic units results most probably (i) from the condensation of a C2 unit derived from pyruvate decarboxylation (e.g. thiamine-activated acetaldehyde) on the C-2 carbonyl group of a triose phosphate derivative issued probably from dihydroxyacetone phosphate and not from pyruvate and (ii) from a transposition step. Although this hypothetical biosynthetic pathway resembles that of L-valine biosynthesis, this amino acid or its C5 precursors could be excluded as intermediates in the formation of isoprenic units.

Abstract
Several lines of evidence suggest that Gram-positive bacterial cell surface polymers are synthesized by stepwise addition of polymer subunits to an amphipathic acceptor. In the case of membrane-bound lipopolymers such as mannan and lipoteichoic acid, the finished product may be covalently linked to a lipid anchor. In the case of polymers that are transferred into preexisting cell wall, such as teichoic acid and peptidoglycan, two alternative fates might be possible: (1) transfer into wall with concomitant or later cleavage of the lipid anchor, with recycling of the lipid anchor or secretion of the lipid anchor into the growth medium, and (2) transfer into wall without cleavage of the lipid anchor, resulting in maintenance of the covalent relationship between lipid anchor and polymer chain. In the latter case, a close relationship should be established between the cell wall and the plasma membrane. A number of Gram-positive bacteria have been shown to be resistant to plasmolysis. Therefore, a model for the assembly of the Gram-positive cell wall is proposed which takes into account a role for lipopolymeric intermediates and which views the establishment of resistance to plasmolysis as the natural consequence of such a mechanism.

Abstract
The formation of the components of the cell envelope of Acinetobacter sp. 199A was investigated by measuring the incorporation of [3H]leucine into protein, [14C]galactose into lipopolysaccharide, 32P into phospholipid, and [3H]diaminopimelic acid into peptidoglycan. Whereas the lipopolysaccharide and intrinsic protein of the outer membrane were stable, some of the regularly arranged surface protein, the alpha-protein, was lost into the growth medium. Only newly synthesized alpha-protein was lost. The peptidoglycan of the murein layer was also labile. Selective inhibition of the formation of individual components of the cell envelope with penicillin, chloramphenicol, and bacitracin showed that incorporation of protein into the outer membrane required the simultaneous formation of complete lipopolysaccharide. The converse was not true: protein synthesis was not required for lipopolysaccharide incorporation. Formation of the outer membrane and the murein layer proceeded independently.

Abstract
Endogenous dolichol was shown to function as a natural acceptor of mannose residues by using regenerating rat liver containing [(3)H]dolichol. When subcellular fractions from this liver were incubated with GDP-[(14)C]mannose a double-labelled lipid, which represented 30% of the total [(14)C]mannolipid, could be isolated. This lipid was shown to be identical with the dolichol phosphate mannose formed from exogenous dolichol phosphate, by chromatography, stability to alkali and by chemical cleavage to mannose and dolichol derivatives. It was formed by the rough endoplasmic reticulum and mitochondria. If it is concerned in glycoprotein synthesis this would suggest that it functions in the formation of both secreted and mitochondrial glycoproteins. When both the dolichol and retinol of rat tissue were radioactive they made similar contributions to the synthesis of the lipid by liver microsomal fractions and intestinal epithelial cells.
