Organization and expression of a Thermus thermophilus arginine cluster: presence of unidentified open reading frames and absence of a Shine-Dalgarno sequence.

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
A group of genes regulated by arginine was found clustered in the order argF-ORF1-argC-argJ-ORF4 between other, as yet uncharacterized, open reading frames (ORFs). Transcription starts were identified immediately upstream from argF and ORF4. Arginine repressed transcription that was initiated at argF but induced transcription of ORF4. The functions of ORF1 and ORF4 are unknown, but analysis of the sequence of ORF4 suggests that it is a membrane protein, possibly involved in transport of arginine or a related metabolite. Mobility shift and DNase I footprinting have revealed specific binding of pure Escherichia coli ArgR to the promoter region of Thermus thermophilus argF. These results suggest that argF transcription is controlled by a repressor homologous to those characterized in enteric bacteria and bacilli. Thermus argF mRNA is devoid of Shine-Dalgarno (SD) sequences. However, downstream from the ATG start codon of argF and many other Thermus genes (with or without an SD box), sequences were found to be complementary to nucleotides 1392 to 1409 of Thermus 16S rRNA, suggesting that an mRNA-rRNA base pairing in this region is important for correct translation initiation.
