The exemplars for this family are the PhoD protein of Bacillus subtilis and the phospholipase D of Streptomyces chromofuscus. We present the crystal structure of B. subtilis PhoD. PhoD is most closely related to purple acid phosphatases (PAPs) with both types of enzyme containing a tyrosinate-ligated Fe3+ ion. However, the PhoD active site diverges from that found in PAPs and uses two Ca2+ ions instead of the single extra Fe2+, Mn2+, or Zn2+ ion present in PAPs. The PhoD crystals contain a phosphate molecule that co-ordinates all three active site metal ions and which is proposed to represent a product complex. A C-terminal helix lies over the active site and controls access to the catalytic centre. The structure of PhoD defines a new phosphatase active site architecture based on Fe3+ and Ca2+ ions.
