(A) Domain architecture of αB: an N-terminal domain essential for oligomerization, an α-crystallin domain involved in dimerization, and a C-terminal domain containing the conserved IXI motif. (B) 2D 1H-13C INEPT MAS solid-state NMR spectrum show flexible residues in N and C termini; assignments from Carver et al. (15) are indicated with dotted lines.
