DNA repair protein (mre11); All proteins in this family for which functions are known are subunits of a nuclease complex made up of multiple proteins including MRE11 and RAD50 homologs. The functions of this nuclease complex include recombinational repair and non-homolgous end joining. This family is based on the phylogenomic analysis of JA Eisen (1999, Ph.D. Thesis, Stanford University). The proteins in this family are distantly related to proteins in the SbcCD complex of bacteria. [DNA metabolism, DNA replication, recombination, and repair]

Mre11 nuclease, N-terminal metallophosphatase domain; Mre11 (also known as SbcD in Escherichia coli) is a subunit of the MRX protein complex. This complex includes: Mre11, Rad50, and Xrs2/Nbs1, and plays a vital role in several nuclear processes including DNA double-strand break repair, telomere length maintenance, cell cycle checkpoint control, and meiotic recombination, in eukaryotes. During double-strand break repair, the MRX complex is required to hold the two ends of a broken chromosome together. In vitro studies show that Mre11 has 3'-5' exonuclease activity on dsDNA templates and endonuclease activity on dsDNA and ssDNA templates. In addition to the N-terminal phosphatase domain, the eukaryotic MRE11 members of this family have a C-terminal DNA binding domain (not included in this alignment model). MRE11-like proteins are found in prokaryotes and archaea was well as in eukaryotes. Mre11 belongs to the metallophosphatase (MPP) superfamily. MPPs are functionally diverse, but all share a conserved domain with an active site consisting of two metal ions (usually manganese, iron, or zinc) coordinated with octahedral geometry by a cage of histidine, aspartate, and asparagine residues. The MPP superfamily includes: Mre11/SbcD-like exonucleases, Dbr1-like RNA lariat debranching enzymes, YfcE-like phosphodiesterases, purple acid phosphatases (PAPs), YbbF-like UDP-2,3-diacylglucosamine hydrolases, and acid sphingomyelinases (ASMases). The conserved domain is a double beta-sheet sandwich with a di-metal active site made up of residues located at the C-terminal side of the sheets. This domain is thought to allow for productive metal coordination.

Mre11 DNA-binding presumed domain; The Mre11 complex is a multi-subunit nuclease that is composed of Mre11, Rad50 and Nbs1/Xrs2, and is involved in checkpoint signalling and DNA replication. Mre11 has an intrinsic DNA-binding activity that is stimulated by Rad50 on its own or in combination with Nbs1.

Bacillus subtilis YkuE and related proteins, C-terminal metallophosphatase domain; YkuE is an uncharacterized Bacillus subtilis protein with a C-terminal metallophosphatase domain and an N-terminal twin-arginine (RR) motif. An RR-signal peptide derived from the Bacillus subtilis YkuE protein can direct Tat-dependent secretion of agarase in Streptomyces lividans. This is an indication that YkuE is transported by the Bacillus subtilis Tat (Twin-arginine translocation) pathway machinery. YkuE belongs to the metallophosphatase (MPP) superfamily. MPPs are functionally diverse, but all share a conserved domain with an active site consisting of two metal ions (usually manganese, iron, or zinc) coordinated with octahedral geometry by a cage of histidine, aspartate, and asparagine residues.
