General annotation (Comments)

Function

Ubiquitin thioesterase component of the regulatory network controlling carbon source utilization through ubiquitination and deubiquitination involving creA, creB, creC, creD and acrB. Deubiquitinates the creA catabolic repressor and the quinate permease qutD. Plays also a role in response to carbon starvation and the control of extracellular proteases activity By similarity.

Catalytic activity

Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal).

Subunit structure

Interacts with creA, creC and qutD By similarity.

Sequence similarities

Belongs to the peptidase C19 family.

Contains 1 USP domain.

Sequence caution

The sequence EAU36447.1 differs from that shown. Reason: Erroneous gene model prediction.
