We have studied a possible evolution process permitting a 'primitive' membrane to evolve towards a membrane structure with an outer wall, similar to that of bacteria. We have investigated whether a polysaccharide bearing hydrophobic phytyl or cholest

The monolayer properties of some single-chain polyprenyl phosphates (phytanyl, phytyl, and geranylgeranyl phosphates), which we regard as hypothetical primitive membrane lipids, were investigated at the air-water interface by surface pressure-area (p

1. A cell-free system from the protozoon Tetrahymena pyriformis was incubated with either [12-3H]squalene or (RS)-2,3-epoxy-2,3-dihydro-[12,13-3H]squalene. Squalene was cyclized into tetrahymanol whereas racemic squalene epoxide was transformed into

1. A cell-free system from the bacterium Methylococcus capsulatus was incubated with [12-3H]-squalene; diploptene and diplopterol, normally present in the bacterium, were labelled. 2 The same cell-free system was incubated with (RS)-2,3-epoxy-2,3-dih

1. A cell-free system from the bacterium Acetobacter pasteurianum was incubated with [12-3H]squalene; diploptene and diplopterol, hopanoids normally present in the bacterium, were labelled. Their radioactivity was confirmed by purification using thin

Mixtures of the rigid amphiphile disodium cholesteryl phosphate (DCP) with the non-phosphorylated diacyl amphiphile dimyristoylglycerol (DMG) give self-organized systems in a wide range of pH, as demonstrated by differential microcalorimetry. These s
