RC STRAIN=DSM 44908 {ECO:0000313|EMBL:SFA62615.1, RC ECO:0000313|Proteomes:UP000182054}; RA de Groot N.N.; RL Submitted (OCT-2016) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Protein modifier that is covalently attached to lysine CC residues of substrate proteins, thereby targeting them for CC proteasomal degradation. The tagging system is termed pupylation. CC {ECO:0000256|HAMAP-Rule:MF_02106, ECO:0000256|SAAS:SAAS00276152}. CC -!- PATHWAY: Protein degradation; proteasomal Pup-dependent pathway. CC {ECO:0000256|HAMAP-Rule:MF_02106, ECO:0000256|SAAS:SAAS00373196}. CC -!- SUBUNIT: Strongly interacts with the proteasome-associated ATPase CC ARC through a hydrophobic interface; the interacting region of Pup CC lies in its C-terminal half. There is one Pup binding site per ARC CC hexamer ring. {ECO:0000256|HAMAP-Rule:MF_02106}. CC -!- DOMAIN: The N-terminal unstructured half of Pup provides a signal CC required to initiate unfolding and degradation by the proteasome CC but is not needed for pupylation, while the C-terminal helical CC half of Pup interacts with ARC to target proteins to the CC proteasome. {ECO:0000256|HAMAP-Rule:MF_02106}. CC -!- PTM: Is modified by deamidation of its C-terminal glutamine to CC glutamate by the deamidase Dop, a prerequisite to the subsequent CC pupylation process. {ECO:0000256|HAMAP-Rule:MF_02106}. CC -!- SIMILARITY: Belongs to the prokaryotic ubiquitin-like protein CC family. {ECO:0000256|HAMAP-Rule:MF_02106, CC ECO:0000256|SAAS:SAAS00562934}.
