From: Deriving enzymatic and taxonomic signatures of metagenomes from short read data
Raw factors. Factors defined as (number of SP hits)/(number of enzymatic genes) for E. coli on SR ensembles with different lengths (numbers of nucleotides). Displayed are four 3rd-level EC categories that possess the largest factors. The x-scale is the inverse of the read-length. The values of the different lengths are denoted within the figure. The extreme points at 1/read-length = 0 correspond to factors evaluated from the full genome length. The latter coincide with values derived from the full proteome.
