Fig 5. The pathway of sulfate assimilation from different Blattabacterium strains.

(a). Genes required for sulfur assimilation (b) include cysN and cysD coding for two subunits of sulfate adenyltransferase; the adenosine 5’-phosphosulfate (APS) reductase cysH and the sulfite reductase cysIJ. 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.
