HHsearch alignment for GI: 254780594 and conserved domain: cd03033

>cd03033 ArsC_15kD Arsenate Reductase (ArsC) family, 15kD protein subfamily; composed of proteins of unknown function with similarity to thioredoxin-fold arsenic reductases, ArsC. It is encoded by an ORF present in a gene cluster associated with nitrogen fixation that also encodes dinitrogenase reductase ADP-ribosyltransferase (DRAT) and dinitrogenase reductase activating glycohydrolase (DRAG). ArsC catalyzes the reduction of arsenate [As(V)] to arsenite [As(III)], using reducing equivalents derived from glutathione via glutaredoxin, through a single catalytic cysteine.
