The thiamine kinase (YcfN) enzyme plays a minor but significant role in cobinamide salvaging in Salmonella enterica.

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
Cobinamide (Cbi) salvaging is impaired, but not abolished, in a Salmonella enterica strain lacking a functional cobU gene. CobU is a bifunctional enzyme (NTP:adenosylcobinamide [NTP:AdoCbi] kinase, GTP:adenosylcobinamide-phosphate [GTP:AdoCbi-P] guanylyltransferase) whose AdoCbi kinase activity is necessary for Cbi salvaging in this bacterium. Inactivation of the ycfN gene in a DeltacobU strain abrogated Cbi salvaging. Introduction of a plasmid carrying the ycfN(+) allele into a DeltacobU DeltaycfN strain substantially restored Cbi salvaging. Mass spectrometry data indicate that when YcfN-enriched cell extracts were incubated with AdoCbi and ATP, the product of the reaction was AdoCbi-P. Results from bioassays confirmed that YcfN converted AdoCbi to AdoCbi-P in an ATP-dependent manner. YcfN is a good example of enzymes that are used by the cell in multiple pathways to ensure the salvaging of valuable precursors.
