| catalytic Activity | CATALYTIC ACTIVITY: Reaction=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).; EC=3.4.19.12; |
| DNA Binding | |
| EC Number | 3.4.19.12 |
| Enzyme Function | FUNCTION: Required for proper prespore cell patterning. Plays a role in stabilizing mkkA by preventing it from being targeted for degradation. ubcB and ubpB differentially control ubiquitination/deubiquitination and degradation of mkkA in a cell-type-specific and temporally regulated manner. {ECO:0000269|PubMed:9832508}. |
