LSU ribosomal protein L40E (CEP52); Similar to PIR:B48470 percent identity: 61.11; identified by sequence similarity; putative; Belongs to the eukaryotic ribosomal protein eL40 family.

GTP-binding protein homologue (yphC); Similar to PID:1146219 SP:P50743 GB:AL009126 percent identity: 26.99; identified by sequence similarity; putative.

Proteasome regulatory AAA-ATPase; 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-20 [...]

Proteasome, subunit alpha (psmA); Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The M.jannaschii proteasome is able to cleave oligopeptides after Glu, Asp, Tyr, Phe, Trp, slightly after Arg, but not after Ala. Thus, displays caspase-like and chymotrypsin-like activities and low level of trypsin- like activity.

Arsenical pump-driving ATPase (arsA); Anion-transporting ATPase. Catalyzes the extrusion of arsenite (By similarity).

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.

Proteasome, subunit beta (psmB); Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The M.jannaschii proteasome is able to cleave oligopeptides after Glu, Asp, Tyr, Phe, Trp, slightly after Arg, but not after Ala. Thus, displays caspase-like and chymotrypsin-like activities and low level of trypsin- like activity.

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.

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).
