Title: Structure and specificity of FEN-1 from Methanopyrus kandleri

DNA repair is fundamental to genome stability and is found in all three domains of life. However, many archaeal species, such as Methanopyrus kandleri, contain only a subset of the eukaryotic nucleotide excision repair (NER) homologues, and those present often contain significant differences compared to their eukaryotic homologues. To clarify the role of the NER XPG-like protein Mk0566 from M. kandleri, its biochemical activity and three dimensional structure were investigated. Ultimately, we found both to be more similar to human FEN-1 than human XPG, suggesting a biological role in replication and long-patch base excision repair rather than in NER.
