Crystal structure of the Bacillus subtilis phosphodiesterase PhoD reveals an iron and calcium-containing active site.
The PhoD family of extra-cytoplasmic phosphodiesterases are among the most commonly occurring bacterial phosphatases. 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 Fe(3+) ion. However, the PhoD active site diverges from that found in PAPs an...Expand abstract
