CC   -!- FUNCTION: Protein modifier that is covalently attached to lysine
CC       residues of substrate proteins, thereby targeting them for proteasomal
CC       degradation. The tagging system is termed pupylation. Among the
CC       identified substrates are the FabD, PanB and Mpa proteins (By
CC       similarity). {ECO:0000250}.
CC   -!- PATHWAY: Protein degradation; proteasomal Pup-dependent pathway.
CC   -!- SUBUNIT: Strongly interacts with the proteasome-associated ATPase ARC
CC       (Mpa) through a hydrophobic interface; the interacting region of Pup
CC       lies in its C-terminal half. {ECO:0000250}.
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:0000250}.
CC   -!- SIMILARITY: Belongs to the prokaryotic ubiquitin-like protein family.
CC       {ECO:0000305}.
