MURINE/HUMAN UBIQUITIN-CONJUGATING ENZYME UBC9
OverviewOverview
Murine/human ubiquitin-conjugating enzyme Ubc9 is a functional homolog of, Saccharomyces cerevisiae Ubc9 that is essential for the viability of yeast, cells with a specific role in the G2-M transition of the cell cycle. The, structure of recombinant mammalian Ubc9 has been determined from two, crystal forms at 2.0 A resolution. Like Arabidopsis thaliana Ubc1 and S., cerevisiae Ubc4, murine/human Ubc9 was crystallized as a monomer, suggesting that previously reported hetero- and homo-interactions among, Ubcs may be relatively weak or indirect. Compared with the known crystal, structures of Ubc1 and Ubc4, which regulate different cellular processes, Ubc9 has a 5-residue insertion that forms a very exposed tight, beta-hairpin and a 2-residue insertion that forms a bulge in a loop close, to ...
