CC   -!- FUNCTION: ATPase which is responsible for recognizing, binding,
CC       unfolding and translocation of pupylated proteins into the bacterial
CC       20S proteasome core particle. May be essential for opening the gate of
CC       the 20S proteasome via an interaction with its C-terminus, thereby
CC       allowing substrate entry and access to the site of proteolysis. Thus,
CC       the C-termini of the proteasomal ATPase may function like a 'key in a
CC       lock' to induce gate opening and therefore regulate proteolysis.
CC       {ECO:0000255|HAMAP-Rule:MF_02112}.
CC   -!- PATHWAY: Protein degradation; proteasomal Pup-dependent pathway.
CC       {ECO:0000255|HAMAP-Rule:MF_02112}.
CC   -!- SUBUNIT: Homohexamer. Assembles into a hexameric ring structure that
CC       caps the 20S proteasome core. Strongly interacts with the prokaryotic
CC       ubiquitin-like protein Pup through a hydrophobic interface; the
CC       interacting region of ARC lies in its N-terminal coiled-coil domain.
CC       There is one Pup binding site per ARC hexamer ring. Upon ATP-binding,
CC       the C-terminus of ARC interacts with the alpha-rings of the proteasome
CC       core, possibly by binding to the intersubunit pockets.
CC       {ECO:0000255|HAMAP-Rule:MF_02112}.
CC   -!- DOMAIN: Consists of three main regions, an N-terminal coiled-coil
CC       domain that binds to protein Pup and functions as a docking station, an
CC       interdomain involved in ARC hexamerization, and a C-terminal ATPase
CC       domain of the AAA type. {ECO:0000255|HAMAP-Rule:MF_02112}.
CC   -!- DISRUPTION PHENOTYPE: Mutants show a reduction in the in vivo growth
CC       rate, but still persist in mouse lungs, and elicit reduced levels of
CC       interferon-gamma production in the lungs. Expression of the genes lat
CC       and MT3159 are highly up-regulated. {ECO:0000269|PubMed:17041849}.
CC   -!- BIOTECHNOLOGY: When used as an immunizing agent, the mpa deletion
CC       mutant provides significant protection against challenge with a
CC       virulent strain of M.tuberculosis. It shows interesting properties as a
CC       live attenuated vaccine for tuberculosis and could play a role in
CC       generating a safe and effective M.tuberculosis-derived vaccine.
CC       {ECO:0000269|PubMed:17041849}.
CC   -!- SIMILARITY: Belongs to the AAA ATPase family. {ECO:0000255|HAMAP-
CC       Rule:MF_02112}.
