a, Distribution of genes related to the de novo NAD+ and quinolinate biosynthetic pathways in P. coloniale (orange) as compared with Rhodoplantae (red), Glaucoplantae (purple), early-diverging Chlorophyta (blue), early-diverging Streptophyta (green) and bacteria (brown). Solid circles denote the presence of homologues in each clade. TDO/IDO, tryptophan-/indoleamine 2,3-dioxygenase; AFM, arylformamidase; KMO, kynurenine 3-monooxygenase; KYU, kynureninase; HAAO, 3-hydroxyanthranilate 3,4-dioxygenase; ACMSD, 2-amino-3-carboxymuconate-6-semialdehyde decarboxylase; AO, l-aspartate oxidase; QS, quinolinate synthase. b, A gene fusion architecture between KYU and HAAO of P. coloniale; the left and right parts are the KYU and HAAO genes, respectively. A comparison of sequence similarity of various KYU and HAAO genes from different organisms is shown.
