Structural basis for the interaction of the fluorescence probe 8-anilino-1-naphthalene sulfonate (ANS) with the antibiotic target MurA.
E.Schonbrunn, S.Eschenburg, K.Luger, W.Kabsch, N.Amrhein.
The extrinsic fluorescence dye 8-anilino-1-naphthalene sulfonate (ANS) is widely used for probing conformational changes in proteins, yet no detailed structure of ANS bound to any protein has been reported so far. ANS has been successfully used to monitor the induced-fit mechanism of MurA [UDPGlcNAc enolpyruvyltransferase (EC )], an essential enzyme for bacterial cell wall biosynthesis. We have solved the crystal structure of the ANS small middle dotMurA complex at 1.7-A resolution. ANS binds at an originally solvent-exposed region near Pro-112 and induces a major restructuring of the loop Pro-112-Pro-121, such that a specific binding site emerges. The fluorescence probe is sandwiched between the strictly conserved residues Arg-91, Pro-112, and Gly-113. Substrate binding to MurA is accompanied by large movements especially of the loop and Arg-91, which explains why ANS is an excellent sensor of conformational changes during catalysis of this pharmaceutically important enzyme.

Figure 3.
Fig. 3. The ANS binding site in MurA. (Upper) Representation of the F[o] F[c] difference density contoured at 3 in the region of the ANS binding site. ANS was omitted in the refinement and the calculation of the Fourier synthesis. (Lower) The final 2F[o] F[c] electron density contoured at 1 . ANS was included in the refinement and the calculation of the Fourier synthesis. Carbon atoms are colored yellow, nitrogen atoms blue, oxygen atoms red, sulfur atoms green. Solvent molecules are shown as red spheres. Thick dashed lines represent hydrogen bonds. To designate hydrophobic interactions, distances between ring centers and closest carbon atoms are given along thin dashed lines. The figure was drawn with BOBSCRIPT (22).
Figure 4.
Fig. 4. Conformational changes in the loop around Cys-115. Stereo representations of the loop in unliganded MurA[type2] (11) (A), ANS-liganded MurA (B), and the closed state of MurA (7) (C). Arg-91 (yellow), the ANS molecule (orange), and the main chain of the loop Pro-112-Gly-Gly-Cys-Ala-Ile-Gly-Ala-Arg-Pro-121 together with the side chains of Pro-112, Cys-115, and Pro-121 (magenta) are represented as ball and stick. Noncarbon atoms are color-coded as in Fig. 3. Turquoise spheres and dashed lines designate water molecules and hydrogen bonds, respectively. The surrounding protein is shown as a gray -carbon trace. The view corresponds to a zoom of Fig. 2. The structures were aligned through residues Asp-231, Asp-305, Arg-371, and Arg-331 of the bottom domain of MurA.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
