1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Archaea produce membrane lipids that typically possess fully saturated isoprenoid hydrocarbon chains attached to the glycerol moiety via ether bonds. They are functionally similar to, but structurally and biosynthetically distinct from, the fatty acid-based membrane lipids of bacteria and eukaryotes. It is believed that the characteristic lipid structure helps archaea survive under severe conditions such as extremely low or high pH, high salt concentrations, and/or high temperatures. We detail here the first successful production of an intact archaeal membrane lipid, which has fully saturated isoprenoid chains, in bacterial cells. The introduction of six phospholipid biosynthetic genes from a methanogenic archaeon, Methanosarcina acetivorans, in Escherichia coli enabled the host bacterium to synthesize the archaeal lipid, i.e., diphytanylglyceryl phosphoglycerol, while a glycerol modification of the phosphate group was probably catalyzed by endogenous E. coli enzymes. Reduction of the isoprenoid chains occurred only when archaeal ferredoxin was expressed with geranylgeranyl reductase, suggesting the role of ferredoxin as a specific electron donor for the reductase. This report is the first identification of a physiological reducer for archaeal geranylgeranyl reductase. On the other hand, geranylgeranyl reductase from the thermoacidophilic archaeon Sulfolobus acidocaldarius could, by itself, replace both its orthologue and ferredoxin from M. acetivorans, which indicated that an endogenous redox system of E. coli reduced the enzyme.
