Ribosomal RNA-processing protein RRP4; Non-catalytic component of the exosome, which is a complex involved in RNA degradation. Increases the RNA binding and the efficiency of RNA degradation. Confers strong poly(A) specificity to the exosome.

Ribosomal RNA-processing protein RRP41/SKI6; Catalytic component of the exosome, which is a complex involved in RNA degradation. Has 3'->5' exoribonuclease activity. Can also synthesize heteropolymeric RNA-tails.

Ribosomal RNA-processing protein RRP42; Non-catalytic component of the exosome, which is a complex involved in RNA degradation. Contributes to the structuring of the Rrp41 active site.

Prefoldin, beta subunit; Molecular chaperone capable of stabilizing a range of proteins. Seems to fulfill an ATP-independent, HSP70-like function in archaeal de novo protein folding.

Translation elongation factor 2 (EF-2/EF-G); Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. [...]

Translation initiation factor 6 (aeIF-6); Binds to the 50S ribosomal subunit and prevents its association with the 30S ribosomal subunit to form the 70S initiation complex.

Proteasome endopeptidase complex; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation.

SSU ribosomal protein S19E; May be involved in maturation of the 30S ribosomal subunit. Belongs to the eukaryotic ribosomal protein eS19 family.
