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

This entry represents the second calcineurin-like nuclease domain of DNA double-strand break repair protein Mre11 from Pyrococcus furiosus and similar archaeal proteins. Mre11, also known as Mre11 nuclease, is part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. This domain shows a beta-sheet and two alpha-helices [1-3].	Domain
