Methanospirillum hungatei
(NCBI TaxID 2203,
species name lookup)
Taxonomic group: archaea / Euryarchaeota
(Phylum: Euryarchaeota)
NCBI PubMed ID: 7918605Publication DOI: 10.1016/0005-2760(94)90069-8Journal NLM ID: 0217513Publisher: Elsevier

Acyclic, standard tetraether and diether lipids each account for about 50% of the total ether lipids found in Methanospirillum hungatei. Sixteen ether lipids were purified and defined according to relative weight percentage and staining reactions on thin-layer plates. Structures were elucidated for six previously uncharacterized tetraether lipids. Four of these lipids had as one head group either α-Glcp-(1-2)-β-gal(f)-, or β-gal(f)-(1-6)-β-gal(f)-, in glycosidic linkage to the first glycerol of the lipid backbone, and either a N,N-dimethyl-aminopentanetetrol or a N,N,N-trimethylaminopentanetetrol moiety in phosphodiester linkage to the second glycerol of the backbone. A fifth lipid was a tetraether structure novel in having carbohydrate moieties at both head group positions; namely α-Glcp-(1-2)-gal(f)- and β-gal(f)-. Two other lipids, a diether and a tetraether, had a single head group consisting of α-Glcp-(1-2)-β-gal(f)- modified by O-acetylation of the gal(f) residue at C-6. In addition to the seven new lipids described above, diether and tetraether analogs of phosphatidylglycerol were found.
