CC -!- FUNCTION: Catalyzes the covalent attachment of the prokaryotic
CC ubiquitin-like protein modifier Pup to the proteasomal substrate
CC proteins, thereby targeting them for proteasomal degradation. This
CC tagging system is termed pupylation. The ligation reaction involves the
CC side-chain carboxylate of the C-terminal glutamate of Pup and the side-
CC chain amino group of a substrate lysine. {ECO:0000255|HAMAP-
CC Rule:MF_02111}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + [prokaryotic ubiquitin-like protein]-L-glutamate +
CC [protein]-L-lysine = ADP + phosphate + N(6)-([prokaryotic ubiquitin-
CC like protein]-gamma-L-glutamyl)-[protein]-L-lysine.; EC=6.3.1.19;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_02111};
CC -!- PATHWAY: Protein degradation; proteasomal Pup-dependent pathway.
CC {ECO:0000255|HAMAP-Rule:MF_02111}.
CC -!- PATHWAY: Protein modification; protein pupylation. {ECO:0000255|HAMAP-
CC Rule:MF_02111}.
CC -!- MISCELLANEOUS: The reaction mechanism probably proceeds via the
CC activation of Pup by phosphorylation of its C-terminal glutamate, which
CC is then subject to nucleophilic attack by the substrate lysine,
CC resulting in an isopeptide bond and the release of phosphate as a good
CC leaving group. {ECO:0000255|HAMAP-Rule:MF_02111}.
CC -!- SIMILARITY: Belongs to the Pup ligase/Pup deamidase family. Pup-
CC conjugating enzyme subfamily. {ECO:0000255|HAMAP-Rule:MF_02111}.
