Haloarcula marismortui cytochrome b-561 is encoded by the narC gene in the dissimilatory nitrate reductase operon.

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.
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
The composition of membrane-bound electron-transferring proteins from denitrifying cells of Haloarcula marismortui was compared with that from the aerobic cells. Accompanying nitrate reductase catalytic NarGH subcomplex, cytochrome b-561, cytochrome b-552, and halocyanin-like blue copper protein were induced under denitrifying conditions. Cytochrome b-561 was purified to homogeneity and was shown to be composed of a polypeptide with a molecular mass of 40 kDa. The cytochrome was autooxidizable and its redox potential was -27 mV. The N-terminal sequence of the cytochrome was identical to the deduced amino acid sequence of the narC gene product encoded in the third ORF of the nitrate reductase operon with a unique arrangement of ORFs. The sequence of the cytochrome was homologous with that of the cytochrome b subunit of respiratory cytochrome bc. A possibility that the cytochrome bc and the NarGH constructed a supercomplex was discussed.
