Phosphatase Family ArsC

Phosphatase Classification: Superfamily Cys-based III: Family ArsC

Arsenate reductase (ArsC) [1], is only found in prokaryotes. While known to reduce arsenate to arsenite (a similar reaction to the phosphatase reaction), the B. subtilis gene also has in vitro phosphatase activity.

Eukaryotes (particularly fungi, plants and protists) have different arsenate reductase, Acr2 of [[[Phosphatase_Superfamily_Cys-based_II|Cys-based II superfamily ]] [2].
