Analysis of the conformation of the 3' major domain of Escherichia coli16S ribosomal RNA using site-directed photoaffinity crosslinking.

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 3' major domain of Escherichia coli 16S rRNA, which occupies the head of the small ribosomal subunit, is involved in several functions of the ribosome. We have used a site-specific crosslinking procedure to gain further insights into the higher-order structure of this domain. Circularly permuted RNAs were used to introduce an azidophenacyl group at specific positions within the 3' major domain. Crosslinks were generated in a high-ionic strength buffer that has been used for ribosome reconstitution studies and so enables the RNA to adopt a structure recognized by ribosomal proteins. The crosslinking sites were identified by primer extension and confirmed by assessing the mobility of the crosslinked RNA lariats in denaturing polyacrylamide gels. Eight crosslinks were characterized. Among them, one crosslink demonstrates that helix 28 is proximal to the top of helix 34, and two others show that the 1337 region, located in an internal loop at the junction of helices 29, 30, 41, and 42, is proximal to the center of helix 30 and to a segment connecting helix 28 to helix 29. These relationships of vicinity have previously been observed in native 30S subunits, which suggests that the free domain adopts a conformation similar to that within the 30S subunit. Furthermore, crosslinks were obtained in helix 34, which suggest that the upper and lower portions of this helix are in close proximity.
