DNA bending induced by DNA (cytosine-5) methyltransferases.

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
DNA bending induced by six DNA (cytosine-5) methyltransferases was studied using circular permutation gel mobility shift assay. The following bend angles were obtained: M.BSP:RI (GG(m5)CC), 46-50 degrees; M.HAE:III (GG(m5)CC), 40-43 degrees; M.SIN:I (GGW(m5)CC), 34-37 degrees; M.SAU:96I (GGN(m5)CC), 52-57 degrees; M.HPA:II (C(m5)CGG), 30 degrees; and M.HHA:I (G(m5)CGC), 13 degrees. M. HAE:III was also tested with fragments carrying a methylated binding site, and it was found to induce a 32 degrees bend. A phase-sensitive gel mobility shift assay, using a set of DNA fragments with a sequence-directed bend and a single methyltransferase binding site, indicated that M.HAE:III and M. BSP:RI bend DNA toward the minor groove. The DNA curvature induced by M.HAE:III contrasts with the lack of DNA bend observed for a covalent M.HAE:III-DNA complex in an earlier X-ray study. Our results and data from other laboratories show a correlation between the bending properties and the recognition specificities of (cytosine-5) methyltransferases: enzymes recognizing a cytosine 3' to the target cytosine tend to induce greater bends than enzymes with guanine in this position. We suggest that the observed differences indicate different mechanisms employed by (cytosine-5) methyltransferases to stabilize the helix after the target base has flipped out.
