Figure 4.
Fig. 4. A structural comparison A3G191-384-2K3A (PDB ID code
2kem; this study), A3G193-384 (PDB ID code 2kbo^20), A3G197-380
(PDB ID code 3e1u^22), and A2 (PDB ID code 2nyt^23). (a–d)
α-carbon-traced ribbon schematics for the aforementioned
structures. The β2 regions are highlighted by blue ovals and
shown in green in (b)–(d). The interdomain linker region in
(a) is indicated by an arrow. (e–h) Polypeptide backbone and
chemical contact schematics for the β2 and β1 regions of
A3G191-384-2K3A, A3G193-384, A3G197-380, and A2, respectively.
Amino acid positions are numbered and, if the residue is
conserved, shown in red. In (e) and (f), observed NOEs are
indicated by arrows. In (g) and (h), predicted hydrogen bonds
are indicated by broken lines, and labels correspond to
distances between the amide nitrogen and the carbonyl oxygen
atoms.
