  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.

• Purification and Characterization of Geranylgeranylglyceryl Phosphate Synthase from a Thermoacidophilic Archaeon, Thermoplasma acidophilum

  We purified a geranylgeranylglyceryl phosphate (GGGP) synthase from Thermoplasma acidophilum by several steps of chromatography. Based on the proteinase-fragment-mass-pattern analysis of the SDS-PAGE band of the partially purified protein, the DNA sequence encoding the protein was identified from the whole genome sequence database of the species. The gene encoding GGGP synthase in T. acidophilum was cloned after PCR amplification of the gene from the genomic DNA. The recombinant enzyme was expressed in Escherichia coli and purified. A single band with a molecular mass of 27 kDa was obtained by SDS-PAGE analysis. The apparent native molecular mass of the enzyme was about 50 kDa based on gel filtration chromatography, suggesting that the enzyme is active as a homodimer. As the GGGP synthase from Methanobacterium thermoautotrophicum has been reported as a pentamer, the enzymes of the two organisms have different oligomeric structures. Other characteristics, including substrate specificity, are similar for the GGGPs of these organisms.

  我们采用色谱法对嗜热酸杆菌中的甘油磷酸二烯丙基甘油酯（GGGP）合成酶进行了多步纯化。根据对部分纯化蛋白的SDS-PAGE条带进行的蛋白酶片段质量模式分析，从该物种的全基因组序列数据库中确定了编码该蛋白的DNA序列。在从基因组DNA中PCR扩增嗜热酸杆菌中GGGP合成酶的基因后，将其克隆。重组酶在大肠杆菌中表达并纯化。通过SDS-PAGE分析得到一条分子质量为27 kDa的条带。根据凝胶过滤色谱法，该酶的表观天然分子质量约为50 kDa，表明该酶作为同源二聚体是活跃的。由于来自热自养甲烷杆菌的GGGP合成酶已被报道为五聚体，因此这两种生物的酶具有不同的低聚结构。这些生物的GGGP的其他特征（包括底物特异性）是相似的。
• 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.
