ENZYME entry: EC 6.3.1.19

Accepted Name
Prokaryotic ubiquitin-like protein ligase.
Alternative Name(s)
Proteasome accessory factor A.
Pup ligase.
Pup--protein ligase.
Pup-conjugating enzyme.
Reaction catalysed
ATP + [prokaryotic ubiquitin-like protein]-L-glutamate + [protein]-L-lysine <=> ADP + phosphate + N(6)-([prokaryotic ubiquitin-like protein]-gamma-L-glutamyl)-[protein]-L-lysine
Comment(s)
  • The enzyme has been characterized from the bacteria Mycobacterium tuberculosis and Corynebacterium glutamicum.
  • It catalyzes the ligation of the prokaryotic ubiquitin-like protein (Pup) to a target protein by forming a bond between an epsilon-amino group of a lysine residue of the target protein and the gamma- carboxylate of the C-terminal glutamate of the ubiquitin-like protein (Pup).
  • The attachment of Pup, also known as Pupylation, marks proteins for proteasomal degradation.
  • Formerly EC 6.3.2.n2.
