Fig. 4. Conformational changes induced upon ferrichrome-iron
binding. Superposition of the -carbon
coordinates of FhuA and its complex with ferrichrome-iron
illustrating the ligand-induced conformational changes observed
in the cork domain. The cork domains of FhuA and its complex
with ferrichrome-iron are shown in purple and yellow,
respectively. The barrel strands (shown in blue) are represented
as thin lines for clarity of the cork domain. Apices A, B, and C
and Glu19 are labeled (34).
