Figure 2. (A) TM1394 C-terminal zinc-finger domain in ribbon
representation with zinc (pink sphere) and coordinating cysteine
residues (Cys231, Cys233, Cys263, and Cys266) depicted in
sticks. (B) Superposition of the TM1394 crystallographic dimer
(gray) with the biological dimer of oxidized Hsp33 from E. coli
(chain A, blue; chain B, orange) that contains the domain swap
for residues 178-233. (C) Superposition of zinc sites in TM1394
and Hsp33 from Bacillus subtilis (gray with labels in brackets).
Zn^2+ ions are shown as spheres, and the cysteines, as well as
Tyr270(275) and Arg84(86) residues, are depicted in sticks.
