Figure 2. Stereoviews of the internal UBA domain UBA(1) of
HHR23A (SWISS PROT code R23A_HUMAN) (human homologue of RAD23A)
showing residues Thr156 to Gly204. (a) Ribbon representation.
The three helices are labeled a1, a2, and a3. (b) Superposition
of the ten lowest-energy structures. The backbone atoms are
shown in black for carbon atoms, blue for nitrogen atoms, and
the carbonyl oxygen atoms are omitted. The side-chains for
residues forming the hydrophobic core are shown in green. The
N-terminal residues 155-160 are disordered and are not shown.
