Ubiquitin-mediated proteolysis is a major pathway for selective protein degradation in eukaryotic cells. This proteolysis pathway involves the processive covalent attachment of ubiquitin to proteolytic substrates and their subsequent degradation by a specific ATP-dependent protease complex. We have cloned the genes and characterized the function of ubiquitin-conjugating enzymes (UBCs) from the yeast Saccharomyces cerevisiae. UBC1, UBC4 and UBC5 enzymes were found to mediate selective degradation of short-lived and abnormal proteins. These enzymes have overlapping functions and constitute a UBC subfamily essential for growth. UBC1 is specifically required at early stages of growth after germination of spores. UBC4 and UBC5 enzymes generate high molecular weight ubiquitin-protein conjugates and comprise a major ubiquitin-conjugation activity in yeast cells. Moreover, these enzymes are central components of the cellular stress response.
