A	PF00149	Calcineurin-like phosphoesterase (Metallophos)	Calcineurin-like phosphoesterase	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 ...	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 accessory DNA binding 'capping' domain of Thermotoga maritima Mre11 homologue (SbcD), a subunit of the MRX protein complex involved in DNA double-strand break repair [1,2]. This domain forms the nuclease module with the phosphodiesterase domain at the N-terminal [2].	Domain
