label: URM1 conjugating enzyme activity
label_lc: urm1 conjugating enzyme activity
description: "Isoenergetic transfer of URM1 from one protein to another via the reaction X-URM1 + Y = Y-URM1 + X, where both the X-URM1 and Y-URM1 linkages are thioester bonds between the C-terminal amino acid of URM1 and a sulfhydryl side group of a cysteine residue."
