Figure 1. Degree distribution of the MIN and DN.

Figure 1

Fraction of amino acids versus the normalized degree in the MINs (blue dots) and DNs (orange dots). Degrees were normalized with respect to the average degree. All DNs followed a Poisson distribution (α = 0.01, KS test). 43.8% of MINs followed a power-law distribution and 29.9% followed a Poisson distribution (α = 0.01). Red dots: normalized degree distribution in the MIN for Pfam family PF01432, showing a truncated power-law distribution. Green dots: normalized degree distribution in the MIN for Pfam family PF00118. Logarithmic scale.
