Mechanistic insights into manganese oxidation of a soil-borne Mn(II)-oxidizing Escherichia coli strain by global proteomic and genetic analyses.

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
An iTRAQ-based comparative and quantitative proteomics analysis of a soil-borne Mn(II)-oxidizing bacterium, Escherichia coli MB266, was conducted during the exponential and stationary growth phases. A total of 1850 proteins were identified in 4 samples, of which 373 and 456 proteins were significantly up- or down-regulated in at least one pairwise comparison, respectively. The iTRAQ data indicated that several enzymes involved in fatty acid metabolism (i.e., FabA, FabD and FabZ) and pyruvate metabolism (particularly pyruvate oxidase PoxB) were significantly up-regulated, while those related to the tricarboxylic acid cycle (such as FrdB, FumB and AcnA) and methylcitrate cycle (i.e., PrpC) were inactivated in the presence of 1 mM Mn(II); the amounts of some stress response and signal transduction system-related proteins (i.e., Spy) were remarkably increased, and the cold shock protein CspD was significantly up-regulated during the exponential growth phase. However, all verified heat shock proteins remained unchanged. The reactive oxygen species response and some redox enzymes might also be involved in Mn oxidation processes. The involvement of several cellular proteins in Mn(II) oxidation, including PoxB, Spy and MCO266, was further confirmed by gene disruption and expression complementation experiments. Based on these results, a signal transduction mechanism coupled to Mn oxidation was proposed.
