Abstract excerpt
The higher plant Arabidopsis (Arabidopsis thaliana) has eight genes potentially coding for small ubiquitin-related modifier (SUMO) proteins. However, two well-expressed isoforms differ from fungal and animal consensus in a conserved glutamine (Gln) residue situated four residues from the carboxyl terminus. We tested deviations in this position in the background of SUMO1, the isoform with the highest expression...
