- ubiquitin-like protein transferase activity
Catalysis of the transfer of a ubiquitin-like from one protein to another via the reaction X-ULP + Y = Y-ULP + X, where both X-ULP and Y-ULP are covalent linkages. ULP represents a ubiquitin-like protein.
- Atg8-family conjugating enzyme activity
Isoenergetic transfer of an Atg8 family modifier from one protein to a phosphatidylethanolamine or phosphatidylserine on a membrane, via the reaction X-Atg8 + Y = Y-Atg8 + X.
- MAP kinase kinase activity
Catalysis of the concomitant phosphorylation of threonine (T) and tyrosine (Y) residues in a T-X-Y motif in the activation loop of a MAP kinase (MAPK) substrate.
- FAT10 conjugating enzyme activity
Isoenergetic transfer of FAT10 from one protein to another via the reaction X-FAT10 + Y = Y-FAT10 + X, where both the X-FAT10 and Y-FAT10 linkages are thioester bonds between the C-terminal amino acid of FAT10 and a sulfhydryl side group of a cysteine residue.
