2.A.131.1.1
Exporter, ArsG, of 234 aas and 6 TMSs, specific for trivalent organoarsenicals, 3-amino-4-hydroxybenzene arsonate, HAPA(III) and 3-amino-benzene arsonate, pAsA(III), both of which are aromatic aminobenezylarsenicals (Chen et al. 2019). These compounds are derived from rosarsone (3-nitro-4-hydrolybenzenearsenate or Rox(V)) and nitarsone (3-nitrobenzene arsenate (Nit(V), respectively both used in feed for domestic animals such as chickens to counteract the disease, coccidiosis and improve feed efficiency (Chen et al. 2019). This system has been incorrectly annotated in the UniProt and NCBI protein databases as the "cytochrome c biogenesis protein transmembrane region", and the "sulfite exporter TauE/SafE family protein", respectively.
