Reversibility
arsenate + reduced glutaredoxin
thioredoxin is unable to support arsenate reduction. The N-terminal Cys residue is essential for arsenate reductase activity. During the catalytic cycle, Acr2p forms a mixed disulfide with GSH before being reduced vby glutaredoxin to regenerate the active Acr2p reductase
