The archaeal Xpf/Mus81/FANCM homolog Hef and the Holliday junction resolvase Hjc define alternative pathways that are essential for cell viability in Haloferax volcanii.

Abstract

The XPF/MUS81 family of endonucleases is found in eukaryotes and archaea, in the former they play a critical role in DNA repair and replication fork restart. Hef is a XPF/MUS81 family member found in Euryarchaea and is related to the Fanconi anemia protein FANCM. We have studied the role of Hef in the euryarchaeon Haloferax volcanii. Unlike Xpf in… (More)
