CRYSTAL STRUCTURE OF THE SACCHAROMYCES CEREVISIAE UBIQUITIN-CONJUGATING ENZYME RAD6 (UBC2) AT 2.6A RESOLUTION
Overview
The Saccharomyces cerevisiae ubiquitin-conjugating enzyme (UBC) Rad6 is, required for several functions, including the repair of UV damaged DNA, damage-induced mutagenesis, sporulation, and the degradation of cellular, proteins that possess destabilizing N-terminal residues. Rad6 mediates its, role in N-end rule-dependent protein degradation via interaction with the, ubiquitin-protein ligase Ubr1 and in DNA repair via interactions with the, DNA binding protein Rad18. We report here the crystal structure of Rad6, refined at 2.6 A resolution to an R factor of 21.3%. The protein adopts an, alpha/beta fold that is very similar to other UBC structures. An apparent, difference at the functionally important first helix, however, has, prompted a reassessment of previously reported structures. The ... [(full description)]
