Updated annotation (from data): DNA repair nuclease with dnaQ and GIY-YIG domains Rationale: Specifically important in stress Cisplatin. Contains a domain that is similar to DnaQ (the epsilon subunit of replicative DNA polymerase which is the exonuclease for proofreading) as well as a GIY-YIG nuclease domain.This protein is often misannotated as DnaQ, but the proofreading activity of the replicative DNA polymerase seems to reside in the same polypeptide as the catalytic subunit (see Echvi_2020 or discussion in PMC3919608). Original annotation: exonuclease, DNA polymerase III, epsilon subunit family Type 1: Protein-coding gene Located on scaffold Echvi_Contig97.1, - strand, nucleotides 3,040,834 to 3,042,207 See nucleotide sequence around Echvi_2564 or for all of scaffold Echvi_Contig97.1
