A diphytanyl ether analog of phosphatidylserine from a methanogenic bacterium, Methanobrevibacter arboriphilus.
Several ninhydrin-positive lipids were found in methanogenic bacteria and the structure of one of them, designated as PNL2 from Methanobrevibacter arboriphilus, was identified as a diphytanyl ether analog of phosphatidylserine. The chromatographic behavior of the lipid on thin-layer plates and on a DEAE-cellulose column was identical to the ester form of phosphatidylserine. The infrared spectra...
متن کاملCharacterization of a heme-dependent catalase from Methanobrevibacter arboriphilus.
Recently it was reported that methanogens of the genus Methanobrevibacter exhibit catalase activity. This was surprising, since Methanobrevibacter species belong to the order Methanobacteriales, which are known not to contain cytochromes and to lack the ability to synthesize heme. We report here that Methanobrevibacter arboriphilus strains AZ and DH1 contained catalase activity only when the gr...
متن کاملSynthesis of sulfate esters of phosphatidylglycerol (diphytanyl ether analog).
Synthesis of 1-sn-phosphatidyl-3'-sn-glycero-1'-sulfate (phosphatidylglycero-1-sulfate) was achieved by monosulfation of 1-sn-phosphatidyl-3'-sn-glycerol (diphytanyl ether analog) with an equimolar amount of SO(3)-pyridine complex at room temperature; with excess sulfation reagent at 60 degrees C, the 1',2'-disulfate ester was obtained. The phosphatidyl-glycero-2-sulfate isomer was synthesized ...
متن کاملIdentification of a Ruminococcaceae Species as the Methyl tert-Butyl Ether (MTBE) Degrading Bacterium in a Methanogenic Consortium.
The widespread use of methyl tert-butyl ether (MTBE) has caused major contamination of groundwater sources and is a concern due to its taste and odor problems, as well as its toxicity. MTBE can be degraded anaerobically which makes bioremediation of contaminated aquifers a potential solution. Nevertheless, the organisms and mechanisms that are responsible for anaerobic MTBE degradation are stil...
متن کاملThe Draft Genome of the Non-Host-Associated Methanobrevibacter arboriphilus Strain DH1 Encodes a Large Repertoire of Adhesin-Like Proteins
Methanobrevibacter arboriphilus strain DH1 is an autotrophic methanogen that was isolated from the wetwood of methane-emitting trees. This species has been of considerable interest for its unusual oxygen tolerance and has been studied as a model organism for more than four decades. Strain DH1 is closely related to other host-associated Methanobrevibacter species from intestinal tracts of animal...
