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

Enediyne natural product biosynthesis is characterized by a convergence of multiple pathways, generating unique peripheral moieties that are appended onto the distinctive enediyne core. Kedarcidin (KED) possesses two unique peripheral moieties, a (R)-2-aza-3-chloro-β-tyrosine and an iso-propoxy-bearing 2-naphthonate moiety, as well as two deoxysugars. The appendage pattern of these peripheral moieties to the enediyne core in KED differs from the other enediynes studied to date with respect to stereochemical configuration. To investigate the biosynthesis of these moieties and expand our understanding of enediyne core formation, the biosynthetic gene cluster for KED was cloned from Streptoalloteichus sp. ATCC 53650 and sequenced. Bioinformatics analysis of the ked cluster revealed the presence of the conserved genes encoding for enediyne core biosynthesis, type I and type II polyketide synthase loci likely responsible for 2-aza-l-tyrosine and 3,6,8-trihydroxy-2-naphthonate formation, and enzymes known for deoxysugar biosynthesis. Genes homologous to those responsible for the biosynthesis, activation, and coupling of the l-tyrosine-derived moieties from C-1027 and maduropeptin and of the naphthonate moiety from neocarzinostatin are present in the ked cluster, supporting 2-aza-l-tyrosine and 3,6,8-trihydroxy-2-naphthoic acid as precursors, respectively, for the (R)-2-aza-3-chloro-β-tyrosine and the 2-naphthonate moieties in KED biosynthesis.
