| Enzyme Function | 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. {ECO:0000269|PubMed:10216870, ECO:0000269|PubMed:11442830, ECO:0000269|PubMed:11918805, ECO:0000269|PubMed:12750323, ECO:0000269|PubMed:18512059, ECO:0000269|Ref.8}. |
