Figures & data
Figure 1. STRING database analysis of differentially abundant mitochondrial proteins in dark-cutting vs. normal-pH beef. Mitochondrial protein expression changes induced by the dark-cutting condition in subnetworks identified were compared with normal-pH beef. Red and green colours represent up-regulated and down-regulated proteins (p ≤ 0.05) in dark-cutting beef mitochondrial proteome relative to normal-pH beef. Proteins in clustered circles exhibit protein–protein interactions, while those outside the clusters show no protein–protein interactions.

Figure 2. STRING database analysis of proteins up-and down-regulated in dark-coloured beef at slightly elevated pH vs. normal-pH beef. The proteins with significant changes in protein abundance between dark-coloured beef at slightly elevated pH vs. normal-pH samples were used to query potential protein–protein interactions in the string database as described in the methods. Protein interactions were confirmed with connections, while non-interacting proteins had no connections between them. The red colour represents overabundant proteins and the green colour represents less abundant proteins in dark-coloured beef at slightly elevated pH vs. normal-pH beef. The size of the circle represents fold change in abundance, while the arrowheads indicate the target of the protein interactions.
