  Identification of CDP-Archaeol Synthase, a Missing Link of Ether Lipid Biosynthesis in Archaea

  摘要：

  Archaeal membrane lipid composition is distinct from Bacteria and Eukarya, consisting of isoprenoid chains etherified to the glycerol carbons. Biosynthesis of these lipids is poorly understood. Here we identify and characterize the archaeal membrane protein CDP-archaeol synthase (CarS) that catalyzes the transfer of the nucleotide to its specific archaeal lipid substrate, leading to the formation of a CDP-activated precursor (CDP-archaeol) to which polar head groups are attached. The discovery of CarS enabled reconstitution of the entire archaeal lipid biosynthesis pathway in vitro, starting from simple isoprenoid building blocks and using a set of five purified enzymes. The cell free synthetic strategy for archaeal lipids we describe opens opportunity for studies of archaeal lipid biochemistry. Additionally, insights into archaeal lipid biosynthesis reported here allow addressing the evolutionary hypothesis of the lipid divide between Archaea and Bacteria.

  CDP-2,3-di -O- geranylgeranyl- sn -glycerol: l -serine O -archaetidyltransferase (archaetidylserine synthase) activity in cell extracts of Methanothermobacter thermautotrophicus cells was characterized. The enzyme catalyzed the formation of unsaturated archaetidylserine from CDP-unsaturated archaeol and l -serine. The identity of the reaction products was confirmed by thin-layer chromatography, fast atom bombardment-mass spectrum analysis, and chemical degradation. The enzyme showed maximal activity in the presence of 10 mM Mn ²⁺ and 1% Triton X-100. Among various synthetic substrate analogs, both enantiomers of CDP-unsaturated archaeols with ether-linked geranylgeranyl chains and CDP-saturated archaeol with ether-linked phytanyl chains were similarly active toward the archaetidylserine synthase. The activity on the ester analog of the substrate was two to three times higher than that on the corresponding ether-type substrate. The activity of d -serine with the enzyme was 30% of that observed for l -serine. A trace amount of an acid-labile, unsaturated archaetidylserine intermediate was detected in the cells by a pulse-labeling experiment. A gene (MT1027) in M. thermautotrophicus genome annotated as the gene encoding phosphatidylserine synthase was found to be homologous to Bacillus subtilis pssA but not to Escherichia coli pssA. The substrate specificity of phosphatidylserine synthase from B. subtilis was quite similar to that observed for the M. thermautotrophicus archaetidylserine synthase, while the E. coli enzyme had a strong preference for CDP-1,2-diacyl- sn -glycerol. It was concluded that M. thermautotrophicus archaetidylserine synthase belongs to subclass II phosphatidylserine synthase ( B. subtilis type) on the basis of not only homology but also substrate specificity and some enzymatic properties. The possibility that a gene encoding the subclass II phosphatidylserine synthase might be transferred from a bacterium to an ancestor of methanogens is discussed.

  The basic core structure of archaeal membrane lipids is 2,3-di-O-phytanyl-sn-glyceryl phosphate (archaetidic acid), which is formed by the reduction of 2,3-di-O-geranylgeranylglyceryl phosphate. The reductase activity for the key enzyme in membrane lipid biosynthesis, 2,3-digeranylgeranylglycerophospholipid reductase, was detected in a cell free extract of the thermoacidophilic archaeon Thermoplasma acidophilum. The reduction activity was found in the membrane fraction, and FAD and NADH were required for the activity. The reductase was purified from a cell free extract by ultracentrifugation and four chromatographic steps. The purified enzyme showed a single band at ca. 45 kDa on SDS-PAGE, and catalyzed the formation of archaetidic acid from 2,3-di-O-geranylgeranylglyceryl phosphate. Furthermore, the enzyme also catalyzed the reduction of 2,3-di-O-geranylgeranylglyceryl phosphate analogues such as 2,3-di-O-phytyl-sn-glyceryl phosphate, 3-O-(2,3-di-O-phytyl-sn-glycero-phospho)-sn-glycerol and 2,3-di-O-phytyl-sn-glycero-phosphoethanolamine. The N-terminal 20 amino acid sequence of the purified enzyme was determined and was found to be identical to the sequence encoded by the Ta0516m gene of the T. acidophilum genome. The present study clearly demonstrates that 2,3-digeranylgeranylglycerophospholipid reductase is a membrane associated protein and that the hydrogenation of each double bond of 2,3-digeranylgeranylglycerophospholipids is catalyzed by a single enzyme.

• Specific Partial Reduction of Geranylgeranyl Diphosphate by an Enzyme from the Thermoacidophilic Archaeon <i>Sulfolobus acidocaldarius</i> Yields a Reactive Prenyl Donor, Not a Dead-End Product

  Geranylgeranyl reductase from Sulfolobus acidocaldarius was shown to catalyze the reduction of geranylgeranyl groups in the precursors of archaeal membrane lipids, generally reducing all four double bonds. However, when geranylgeranyl diphosphate was subjected to the reductase reaction, only three of the four double bonds were reduced. Mass spectrometry and acid hydrolysis indicated that the allylic double bond was preserved in the partially reduced product derived from geranylgeranyl diphosphate. Thus, the reaction product was shown to be phytyl diphosphate, which is a substrate for archaeal prenyltransferases, unlike the completely reduced compound phytanyl diphosphate.

  摘要 香叶基纯碱还原酶来自 中的香叶基还原酶 可催化古生膜脂质前体中的香叶基还原基团还原，一般可还原所有四个双键。然而，当对二磷酸香叶酯进行还原酶反应时，四个双键中只有三个被还原。质谱分析和酸水解表明，在二磷酸香叶酯的部分还原产物中保留了烯丙基双键。因此，与完全还原的二磷酸植丹酰化合物不同，反应产物被证明是二磷酸植丹酰，它是古细菌前酰转移酶的底物。
