Circular dichroism data.

<p>Near-UV CD spectra of AaegOBP1 at pH 7 (blue trace) and pH 5.5 (green trace). Disruption of hydrogen bonds that keep the C-terminus covering the binding pocket may account for the changes in the environment of aromatic residues (Phe, Tyr, and/or Trp) at low pH and consequently the decrease in amplitude.
