In-plane diffraction patterns of nucleotides confined in the different environments.
(a) a pure membrane stack, DMPC with AMP, DMPC with UMP and DMPC with AMP/UMP. (b) Lamellar d-spacings for the membrane stacks in part (a). Two spacings are observed in the presence of nucleotides indicative of bilayers with and without a layer of nucleotides between them. (c) In-plane diffraction patterns of nucleotides confined in thin, solid supported films. The patterns are well described by two broad Lorentzian distributions. (d) NH4Cl complexes: The pattern for NH4Cl is well indexed by the known salt structure. Two broad Lorentzian distributions occur in the presence of nucleotides. (e) Diffraction patterns for the Montmorilllonite clay samples. Montmorillonite is a complex structure that shows a rich diffraction pattern, which agrees well with patterns in the literature. Additional broad contributions appear in the presence of the nucleotides. The peak at ~0.4 Å−1 is scattering from the Kapton windows of the X-ray chamber.
