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 -!- SIMILARITY: Belongs to the AAA ATPase family. {ECO:0000255|HAMAP-
CC Rule:MF_02112}.
