DNA repair protein REC; Involved in DNA repair and in homologous recombination. May regulate the cleavage reactions of the branch-structured DNA. Has a very weak ATPase activity that is not stimulated by DNA. Binds DNA but does not promote DNA strands exchange (By similarity).

Proteasome, subunit alpha (psmA); Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation.

Proteasome, subunit beta (psmB); Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation.

Glycerol kinase (glpK); Similar to GB:M34393 SP:P18157 PID:142992 PID:2226137 GB:AL009126 percent identity: 33.83; identified by sequence similarity; putative; Belongs to the FGGY kinase family.

Conserved hypothetical protein; Similar to SP:Q10645 PID:1340100 percent identity: 23.28; identified by sequence similarity; putative.

Proliferating-cell nuclear antigen (pol30); Sliding clamp subunit that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase and other proteins to DNA during high-speed replication. Belongs to the PCNA family.

Methionyl aminopeptidase (map); Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val); Belongs to the peptidase M24A family. Methionine aminopeptidase archaeal type 2 subfamily.

Chemotaxis protein methyltransferase (cheR); Similar to PID:1177141 percent identity: 33.21; identified by sequence similarity; putative.

26S protease regulatory subunit 4; ATPase which is responsible for recognizing, binding, unfolding and translocation of substrate proteins into the archaeal 20S proteasome core particle. Is essential for opening the gate of the 20S proteasome via an interaction with its C-terminus, thereby allowing substrate entry and access to the site of proteolysis. Thus, the C- termini of the proteasomal ATPase function like a 'key in a lock' to induce gate opening and therefore regulate proteolysis. Unfolding activity requires energy from ATP hydrolysis, whereas ATP binding alone promotes ATPase-2 [...]
