Ribonuclease P; Part of ribonuclease P, a protein complex that generates mature tRNA molecules by cleaving their 5'-ends; Belongs to the eukaryotic/archaeal RNase P protein component 2 family.

50S ribosomal protein L15e; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the eukaryotic ribosomal protein eL15 family.

Redox-regulated ATPase YchF; The crystal structure of the Haemophilus influenzae YchF protein showed similarity to the yeast structure (PDB: 1NI3); fluorescence spectroscopy revealed nucleic acid binding; the yeast protein YBR025c interacts with the translation elongation factor eEF1; Derived by automated computational analysis using gene prediction method: Protein Homology.

rRNA metabolism protein; Derived by automated computational analysis using gene prediction method: Protein Homology.

Exosome complex exonuclease Rrp41; Catalytic component of the exosome, which is a complex involved in RNA degradation. Has 3'->5' exoribonuclease activity. Can also synthesize heteropolymeric RNA-tails.

Exosome complex component Rrp42; Non-catalytic component of the exosome, which is a complex involved in RNA degradation. Contributes to the structuring of the Rrp41 active site.

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

RNA-binding protein; 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.
