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

In addition to RNA synthesis, multisubunit RNA polymerases (msRNAPs) support enzymatic reactions such as intrinsic transcript cleavage. msRNAP active sites from different species appear to exhibit differential intrinsic transcript cleavage efficiency and have likely evolved to allow fine-tuning of the transcription process. Here we show that a single amino-acid substitution in the trigger loop (TL) of Saccharomyces RNAP II, Rpb1 H1085Y, engenders a gain of intrinsic cleavage activity where the substituted tyrosine appears to participate in acid-base chemistry at alkaline pH for both intrinsic cleavage and nucleotidyl transfer. We extensively characterize this TL substitution for each of these reactions by examining the responses RNAP II enzymes to catalytic metals, altered pH, and factor inputs. We demonstrate that TFIIF stimulation of the first phosphodiester bond formation by RNAP II requires wild type TL function and that H1085Y substitution within the TL compromises or alters RNAP II responsiveness to both TFIIB and TFIIF. Finally, Mn(2+) stimulation of H1085Y RNAP II reveals possible allosteric effects of TFIIB on the active center and cooperation between TFIIB and TFIIF.
