List of genes associated with amino acid synthesis in all sequenced <i>Blattabacterium</i> strains.

<p>The absent genes are represented by white boxes. Host species abbreviations: BPfu, <i>Periplaneta fuliginosa</i>; BPja, <i>Periplaneta japonica</i>; BNCIN, <i>Nauphoeta cinerea</i>; BGIGA, <i>Blaberus giganteus</i>; BBge, <i>Blattella germanica</i>; BPLAN, <i>Periplaneta americana</i>; BBor, <i>Blatta orientalis</i>; BPAA, <i>Panesthia angustipennis</i>; BCpu, <i>Cryptocercus punctulatus</i>; BMda, <i>Mastotermes darwiniensis</i>. Vertical bars indicate omnivorous (blue), wood-feeding (red), and litter-feeding (black) hosts, respectively. EAA are indicated by orange horizontal bars, and non-EAA indicated by black horizontal bars.</p

Gene order comparison between all <i>Blattabacterium</i> strains.

<p>Lines between genomes connect orthologous genes in blue if genes are in the same orientation, or in green if they are inverted. The first gene in all strains is <i>yidC</i> (membrane protein insertase C).</p

The pathway of sulfate assimilation from different <i>Blattabacterium</i> strains.

<p>(a). Genes required for sulfur assimilation (b) include <i>cysN</i> and <i>cysD</i> coding for two subunits of sulfate adenyltransferase; the adenosine 5’-phosphosulfate (APS) reductase <i>cysH</i> and the sulfite reductase <i>cysIJ</i>. There is a missing step for the conversion of adenosine-5'-phosphosulfate (APS) into 3'-phospho adenosine-5'-phosphosulfate (PAPS). The generated sulfite is reduced to hydrogen sulfide further on assimilated into sulfur-containing amino acids L-cysteine and L-methionine.</p
