Figure 3. (A) The dimeric structure of GluR3 bound to
glutamate. The helices are labeled as in Armstrong et al.[6]
Residues participating in contacts across the dimer interface
are labeled. P632 (yellow) flanks the artificial linker region
of the construct and is the point that connects to the linkers
to the ion channel. The four residues that differ in flip and
flop are shown in shades of red. (B) The dimer interface at the
S754 (flip)/N754 (flop) interaction with S729. Both can form
hydrogen bonds, but the structure of the water surrounding the
hydrogen bond differs.
