Function
Arsenate reductase that plays a major role in the reduction of arsenate to arsenite and arsenic retention in roots (PubMed:16567632). Has an in vitro and in vivo arsenate reductase activity (PubMed:16507083, PubMed:16766666, PubMed:22562211). Plays no role in arsenic metabolism (PubMed:22879969, PubMed:25464340).
