The chemical structure of lipid A from the marine gamma-proteobacterium Pseudoalteromonas haloplanktis ATCC 14393T, a main product of lipopolysaccharide hydrolysis (1% AcOH), was determined using chemical methods and NMR spectroscopy. The lipid A was shown to be beta-1,6-glucosaminobiose 1,4'-diphosphate acylated with two (R)-3-hydroxyalkanoic acid residues(More)
Lipids A from type and wild strains of marine Proteobacteria belonging to Alteromonadaceae (Alteromonas (1 species), Idiomarina (1 species), and Pseudoalteromonas (8 species) genera) and Vibrionaceae (Shewanella (1 species) and Vibrio (1 species) genera) families and Marinomonas genus (1 species) were isolated by hydrolysis of their respective(More)
The chemical structure of a novel lipid A, the major component of the lipopolysaccharide from the marine gamma-proteobacterium Marinomonas vaga ATCC 27119(T), was determined by compositional analysis, NMR spectroscopy, and MS. It was found to be beta-1,6-glucosaminobiose 1-phosphate acylated with (R)-3-[dodecanoyl(dodecenoyl)oxy]decanoic acid [C10 : 0(More)
The chemical structure of a novel lipid A obtained as a major component on hydrolysis of LPS from the marine gamma-proteobacterium Marinomonas vaga ATCC 27119T with 1% AcOH was determined. Using chemical analysis and NMR data, it was shown to be beta-1,6-glucosaminobiose 1-phosphate acylated with R-3-hydroxydecanoic acid (at position 3), and(More)
The amplitude of photoreceptor potential was shown to be constant in hypoxia. Under this condition, the energy support of the photoreceptor potential seems to be realized through an anaerobic process rather than the oxidative phosphorylation. The effect of hypoxia was shown to manifest itself in a decrease of the sagged peak part of the photoreceptor(More)
