Protein Info for CA264_07430 in Pontibacter actiniarum KMM 6156, DSM 19842

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 discussion in PMC3919608).
Original annotation: DNA polymerase III subunit epsilon

These analyses and tools can help you predict a protein's function, but be skeptical. For enzymes, over 10% of annotations from KEGG or SEED are probably incorrect. For other types of proteins, the error rates may be much higher. MetaCyc and Swiss-Prot have low error rates, but the best hits in these databases are often quite distant, so this protein's function may not be the same. TIGRFam has low error rates. Finally, many experimentally-characterized proteins are not in any of these databases. To find relevant papers, use PaperBLAST.
