Proteasome subunit beta; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1B family.

Proteasome ATPase; ATPase which is responsible for recognizing, binding, unfolding and translocation of pupylated proteins into the bacterial 20S proteasome core particle. May be 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 may function like a 'key in a lock' to induce gate opening and therefore regulate proteolysis.

Pup deamidase/depupylase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Pup--protein ligase; Catalyzes the covalent attachment of the prokaryotic ubiquitin-like protein modifier Pup to the proteasomal substrate proteins, thereby targeting them for proteasomal degradation. This tagging system is termed pupylation. The ligation reaction involves the side-chain carboxylate of the C-terminal glutamate of Pup and the side- chain amino group of a substrate lysine.

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

Protein pafC; Derived by automated computational analysis using gene prediction method: Protein Homology.

Transcriptional regulator; Derived by automated computational analysis using gene prediction method: Protein Homology.

DEAD/DEAH box helicase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Preprotein translocase subunit SecA; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatA could form the protein-conducting channel of the Tat system.
