This family includes a diverse range of phosphoesterases [1], including protein phosphoserine phosphatases, nucleotidases, sphingomyelin phosphodiesterases and 2'-3' cAMP phosphodiesterases as well as nucleases such as bacterial SbcD Swiss:P13457 or yeast MRE11 Swiss:P32829. The most conserved regions in this superfamily centre around the metal chelating residues.	Domain
