- Atg12 transferase activity
Catalysis of the transfer of ATG12 from one protein to another via the reaction X-ATG12 + Y = Y-ATG12 + X, where both X-ATG12 and Y-ATG12 are covalent linkages.
- ubiquitin-protein transferase activity
Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y = Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.
- UFM1 transferase activity
Catalysis of the transfer of UFM1 from one protein to another via the reaction X-UFM1 + Y = Y-UFM1 + X, where both X-UFM1 and Y-UFM1 are covalent linkages.
- ISG15 transferase activity
Catalysis of the transfer of ISG15 from one protein to another via the reaction X-ISG15 + Y = Y-ISG15 + X, where both X-ISG15 and Y-ISG15 are covalent linkages.
- FAT10 transferase activity
Catalysis of the transfer of FAT10 from one protein to another via the reaction X-FAT10 + Y = Y-FAT10 + X, where both X-FAT10 and Y-FAT10 are covalent linkages.
