  1. Biosynthetic pathways for the 20 amino acids, citrate and ATP/ADP and GTP/GDP enumerated for E. coli strains where enzymes producing the compounds have been deleted. For each test, columns correspond to: total number of enumerated pathways; number of native pathways in the wild-type strain; percentage of native pathways in the top 10 best ranked pathways; and p-values for the number of genes in E. coli strains top ranked with respect to the total enzyme genes in the database.
