Human recombinant SUMO-2 is produced in E. coli and purified to >95% homogeneity. This protein contains no extraneous tags. Vertebrates express three SUMO homologs, SUMO-1 and the closely related SUMO-2/3, which can be conjugated to substrate proteins in a manner analogous to the ubiquitin system1-3. Although a fourth SUMO (SUMO-4) has been identified in the genome4, it may be an unexpressed pseudogene.
