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

Pyruvate kinase activity is an important element in the flux control of the intermediate metabolism. The purified enzyme from Corynebacterium glutamicum demonstrated a marked sigmoidal dependence of the initial rate on the phosphoenolpyruvate concentration. In the presence of the negative allosteric effector ATP, the phosphoenolpyruvate concentration at the half-maximum rate (S0.5) increased from 1.2 to 2.8 mM, and cooperation, as expressed by the Hill coefficient, increased from 2.0 to 3.2. AMP promoted opposite effects: the S0.5 was decreased to 0.4 mM, and the enzyme exhibited almost no cooperation. The maximum reaction rate was 702 U/mg, which corresponded to an apparent kcat of 2,540 s-1. The enzyme was not influenced by fructose-1,6-diphosphate and used Mn2+ or Co2+ as cations. Sequence determination of the C. glutamicum pyk gene revealed an open reading frame coding for a polypeptide of 475 amino acids. From this information and the molecular mass of the native protein, it follows that the pyruvate kinase is a tetramer of 236 kDa. Comparison of the deduced polypeptide sequence with the sequences of other bacterial pyruvate kinases showed 39 to 44% homology, with some regions being very strongly conserved.
