Fig. 3From: MINEs: open access databases of computationally predicted enzyme promiscuity products for untargeted metabolomicsHistogram of Natural Product Likeness. This plot shows the distribution of Natural Product Likeness Scores for the KEGG Database (mean score 0.77), the KEGG MINE (mean score 0.98) and a random sample of 500,000 PubChem compounds (mean score −0.52). A more positive score indicates more natural atomic features.Back to article page
