Abstract excerpt
Post-translational modifications of proteins by addition of ubiquitin can regulate protein degradation and localization, protein-protein interactions and transcriptional activation. In the ubiquitylation system, substrate specificity is primarily determined by the E2 ubiquitin-conjugating enzyme (UBC) and the E3 ubiquitin ligase. The Arabidopsis thaliana genome contains 37 genes encoding UBC homologs. However,...
