Pup--protein ligase

Gene

pafA

Organism
Amycolatopsis sulphurea
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the covalent attachment of the prokaryotic ubiquitin-like protein modifier Pup to the proteasomal substrate proteins, thereby targeting them for proteasomal degradation. This tagging system is termed pupylation. The ligation reaction involves the side-chain carboxylate of the C-terminal glutamate of Pup and the side-chain amino group of a substrate lysine.UniRule annotation

Miscellaneous

The reaction mechanism probably proceeds via the activation of Pup by phosphorylation of its C-terminal glutamate, which is then subject to nucleophilic attack by the substrate lysine, resulting in an isopeptide bond and the release of phosphate as a good leaving group.UniRule annotation

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.Imported

Catalytic activityi

ATP + [prokaryotic ubiquitin-like protein]-L-glutamate + [protein]-L-lysine = ADP + phosphate + N6-([prokaryotic ubiquitin-like protein]-gamma-L-glutamyl)-[protein]-L-lysine.UniRule annotationSAAS annotation
