3.5.1.119

Accepted name:

Pup amidohydrolase

Reaction:

[prokaryotic ubiquitin-like protein]-L-glutamine + H₂O = [prokaryotic ubiquitin-like protein]-L-glutamate + NH₃

Other name(s):

dop (gene name); Pup deamidase; depupylase/deamidase; DPUP; depupylase

Systematic name:

[prokaryotic ubiquitin-like protein]-L-glutamine amidohydrolase

Comments:

The enzyme has been characterized from the bacterium Mycobacterium tuberculosis. It catalyses the hydrolysis of the amido group of the C-terminal glutamine of prokaryotic ubiquitin-like protein (Pup), thus activating it for ligation to target proteins, a process catalysed by EC 6.3.1.19, prokaryotic ubiquitin-like protein ligase. The reaction requires ATP as cofactor but not its hydrolysis. The enzyme also catalyses the hydrolytic cleavage of the bond formed by the ligase, between an ε-amino group of a lysine residue of the target protein and the γ-carboxylate of the C-terminal glutamate of the prokaryotic ubiquitin-like protein.
