## Figure 4.
Adjacency matrices: random versus ascending CAI. These plots present a view of the
adjacency matrix for the viable bait/prey (VBP) derived from the report from Gavin
and coworkers [10]. An interaction between bait
b and prey p is recorded by a dark pixel in (b,p)th position of the matrix. (a) Rows and columns are randomly ordered; (b) rows and columns are ordered by ascending values of each protein's codon adaptation
index (CAI). Contrasting these two figures, we can ascertain that there is a relationship
between bait/prey interactions and CAI. The relationship is based on proteins with
large un-reciprocated in-degree because panel b shows a dark vertical band. Had unreciprocated
out-degree also been associated with CAI, then there would be a similar horizontal
band reflected across the main diagonal of the matrix.
