Biophysical characterization of a recombinant aminopeptidase II from the thermophilic bacterium Bacillus stearothermophilus.

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
In the present study, the biophysical properties of His6-tagged Bacillus stearothermophilus aminopeptidase II (His6-tagged BsAmpII) are characterized in detail by gel-filtration, analytical ultracentrifugation, and various spectroscopic techniques. Using size-exclusion chromatography and analytical ultracentrifugation, we demonstrate that His6-tagged BsAmpII exists predominantly as a dimer in solution. The enzyme is active and stable at pHs ranging from 6.5 to 8.5. Far-UV circular dichroism analysis reveals that the secondary structures of His6-tagged BsAmpII are significantly altered in the presence of SDS, whereas the presence of 5-10% acetone and ethanol was harmless to the folding of the enzyme. Thermal unfolding of His6-tagged BsAmpII was found to be irreversible and led to the formation of aggregates. The native enzyme started to unfold beyond 0.6 M guanidine hydrochloride and had a midpoint of denaturation at 1.34 M. This protein remained active at concentrations of urea below 2.7 M but experienced an irreversible unfolding by >5 M denaturant. Taken together, this work lays a foundation for potential biotechnological applications of His6-tagged BsAmpII.
