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

The DNA nucleotide thymidylate is synthesized by the enzyme thymidylate synthase, which catalyzes the reductive methylation of deoxyuridylate using the cofactor methylene-tetrahydrofolate (CH(2)H(4)folate). Most organisms, including humans, rely on the thyA- or TYMS-encoded classic thymidylate synthase, whereas, certain microorganisms, including all Rickettsia and other pathogens, use an alternative thyX-encoded flavin-dependent thymidylate synthase (FDTS). Although several crystal structures of FDTSs have been reported, the absence of a structure with folates limits understanding of the molecular mechanism and the scope of drug design for these enzymes. Here we present X-ray crystal structures of FDTS with several folate derivatives, which together with mutagenesis, kinetic analysis, and computer modeling shed light on the cofactor binding and function. The unique structural data will likely facilitate further elucidation of FDTSs' mechanism and the design of structure-based inhibitors as potential leads to new antimicrobial drugs.
