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

Teleocidin B, with its unique indolactam-terpenoid scaffold, is a potent activator of protein kinase C. This short review summarizes our recent research progress on the biosynthesis of teleocidins in Streptomyces blastmyceticus NBRC 12747. We first identified the biosynthetic genes for teleocidin B, which include genes encoding a non-ribosomal peptide synthetase (tleA), a cytochrome P450 monooxygenase (tleB), an indol prenyltransferase (tleC), and a C-methyltransferase (tleD). Notably, the tleD gene is located outside the tleABC cluster. Our in vivo and in vitro analyses revealed that TleD not only catalyzes the C-methylation of the prenyl chain but also produces the indole-fused cyclic terpene structure. This is the first report of terpene cyclization initiated by the C-methylation of the prenyl double bond. In contrast, TleC catalyzes the geranylation of the C-7 position of the indole ring, in the reverse fashion. Our X-ray crystallographic analyses provided the structural basis for the reverse prenylation reactions, and structure-based mutagenesis successfully resulted in the production of unnatural, novel prenylated indolactams.
