G, H	PF09376	NurA domain (NurA)	NurA domain	This family includes NurA a nuclease exhibiting both single-stranded endonuclease activity and 5'-3' exonuclease activity on single-stranded and double-stranded DNA from the hyperthermophilic archaeon Sulfolobus acidocaldarius [2].	Domain

In ATP synthases, this domain is implicated in the assembly of the catalytic toroid and docking of accessory subunits, such as the subunit of the ATP synthase complex. Similar roles in docking of the functional partner, the NurA nuclease, and assembly of the HerA toroid complex appear likely for the HAS-barrel of the HerA family [1].	Domain

This entry represents the central domain found in archaeal proteins such as DNA double-strand break repair helicase HerA (EC:3.6.4.12). HerA is a helicase which is able to utilise either 3' or 5' single-stranded DNA extensions for loading and subsequent DNA duplex unwinding [1]. It forms a complex with NurA nuclease, this complex has the 5'-3' DNA end resection activity and is essential for cell viability in the crenarchaeon Sulfolobus islandicus [2]. This domain includes the the central RecA-like catalytic core and a flanking four-helix bundle [3]. The function of this prokaryotic domain is unknown. It contains several conserved aspartates and histidines that could be metal ligands.	Domain
