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.

Ubiquitin; Protein modifier that is covalently attached to lysine residues of substrate proteins, thereby targeting them for proteasomal degradation. The tagging system is termed pupylation.

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

Phosphate acetyltransferase; Involved in acetate metabolism. In the N-terminal section; belongs to the CobB/CobQ family.

Proteasome subunit alpha; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1A family.

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.

Menaquinone biosynthesis protein; Catalyzes the dehydration of chorismate into 3-[(1- carboxyvinyl)oxy]benzoate, a step in the biosynthesis of menaquinone (MK, vitamin K2).

Sterol-binding protein; Derived by automated computational analysis using gene prediction method: Protein Homology.

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