label: FAT10 conjugating enzyme activity
label_lc: fat10 conjugating enzyme activity
description: "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."
