Figure 1From: A substrate ambiguous enzyme facilitates genome reduction in an intracellular symbiontComparative analysis of the Buchnera pantothenate biosynthesis pathway and complementary A. pisum β-alanine biosynthesis pathways. Metabolic pathways were reconstructed using KEGG pantothenate biosynthesis pathway from E. coli K-12 (eco00770) and from Buchnera from host aphids that included: A. pisum (Ap, buc00770), B. pistaciae (Bp, bab00770), C. cedri (Cc, bcc00770), M. persicae (Mp, [30]), S. graminum (Sg, bas00770) and U. ambrosiae (Ua, bua00770) [34],[35]. Complementary β-alanine biosynthesis pathways of A. pisum (api00410) [34],[35] are shown. The presence/absence of biosynthesis genes in the Buchnera, E. coli and A. pisum genomes is indicated. Full details of A. pisum, Buchnera and E. coli gene identifiers and enzyme activities are provided in Table 1. KEGG, Kyoto Encyclopedia of Genes and Genomes.Back to article page
