A dynamic view of enzyme catalysis.
Article in Journal of molecular modeling, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Recent experimental advances have shown that enzymes are flexible molecules, and point to a direct link between dynamics and catalysis. Movements span a wide time range, from nano- to milli-seconds. In this paper we introduce two aspects of enzyme flexibility that are treated with two appropriate techniques. First, transition path sampling is used to obtain an unbiased picture of the transition state ensemble in chorismate mutase, as well as its local flexibility and the energy flow during the chemical step. Second, we consider the binding and release of substrates in L-rhamnulose-1-phosphate aldolase. We have calculated the normal modes of the enzyme with the elastic network model. The lowest frequency modes generate active site deformations that change the coordination number of the catalytic zinc ion. The coordination lability of zinc allows the binding and release of substrates. Substitution of zinc by magnesium blocks the exchange of ligands.
