Updated annotation (from data): DNA repair nuclease, ligase-associated (TIGR04123) Rationale: Very important for resisting cisplatin. This family was previously annotated as a DNA ligase-associated metallophosphoesterase (TIGR04123). A member of this family (PdeM) has been studied biochemically and found to have nuclease activity, but it was not known if DNA was the physiological substrate (see PMC4320098). Original annotation: DNA ligase-associated metallophosphoesterase Type 1: Protein-coding gene Located on scaffold NC_011916, + strand, nucleotides 2,273,885 to 2,274,592 See nucleotide sequence around CCNA_02122 or for all of scaffold NC_011916
