  Synthesis and Properties of Photoactivatable Phospholipid Derivatives Designed To Probe the Membrane-Associate Domains of Proteins

  摘要：

  The total syntheses of photoactivatable phospholipidic probes 1 and 2 are described. These probes contain either an aryldiazonium function at their polar head (probes la and Ib) or an diazocyclohexadienonyl group attached to the end of one fatty acid side chain (probe 2) and have been designed to probe the lipid/water interface and the hydrophobic core of the membrane, respectively. The synthetic schemes include the possibility of incorporating a radio-labeled atom (tritium) for further labeling investigations. Both probes were stable in the dark under physiological conditions and could be efficiently photodecomposed at wavelengths above 300 nm, leading to the generation of highly reactive species, aryl cations and cyclohexadienonyl carbene, respectively. In addition, these probes displayed UV-absorption spectra which are compatible with tryptophan-mediated energy transfer photoactivation, which can lead potentially to an efficient mapping of the membrane-associate protein domains.

  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.
