Title Crystal structure of the mg·ADP-Inhibited state of the yeast f1c10-Atp synthase.

Abstract
The F(1)c(10) sub-complex of the yeast F(1)F(0)-ATP synthase includes the membrane rotor part c(10)-ring linked to a catalytic head (alpha/beta)(3) by a central stalk (gammadeltaepsilon). The Saccharomyces cerevisiae yF(1)c(10):ADP sub-complex was crystallized in the presence of Mg.ADP, dicyclohexylcarbodiimide (DCCD) and azide. The structure was solved by molecular replacement using a high resolution model of the yeast F(1) and a bacterial c-ring model with 10 copies of the c-subunit. The structure refined to 3.43 A resolution displays new features compared to the original yF(1)c(10) and to the yF(1) inhibited by adenylyl-imidodiphosphate (AMP-PNP) (yF(1)(I-III)). An ADP molecule was bound in both beta(DP) and beta(TP) catalytic sites. The alpha(DP)-beta (DP) pair is slightly open and resembles the novel conformation identified in yF(1) whereas the alpha (TP)-beta(TP) pair is very closed and resembles more a DP pair. yF(1)c(10) provides a model of a new Mg.ADP-inhibited state of the yeast F(1). Like for the original yF(1) and yF(1)c(10):ADP structures, the foot of the central stalk is rotated by about 40 degrees with respect to bovine structures. The assembly of the F(1) central stalk with the F(0) c-ring rotor is mainly provided by electrostatic interactions. On the rotor ring, the essential cGlu(59) carboxylate group is surrounded by hydrophobic residues and is not involved in hydrogen bonding.

Figure 2.
Fig. 2. Stereo views of an electron density map of the yeast F[1]c[10] complex. The solvent flattened map was calculated at 3.9 Å resolution and contoured at 1.5 . (A) Side view containing the bovine F[1] C model (with in orange, in yellow, and in green). The density of symmetry-related molecules in the crystal is masked out. The inset indicates the location of the subunits within the complex. The location of the section shown in (C) is indicated by the white box; the direction of the view is indicated by the arrow. The presumed membrane region (M) (2) is marked by the two dotted lines. The c subunits are numbered 3, 2, 1, 10, and 9 (the best ordered c subunit was chosen as number 1). The overall height of the complex is ~190 Å, of which the [3] [3] subcomplex accounts for 83 Å, the stalk for 50 Å, and the c subunits for 58 Å. (B) Enlarged view of the / -c contact region with the model (and numbering) of the E. coli subunit (in red) and the E. coli c subunit (in white) fitted into the density, contoured at 1.0 . The white box in the inset indicates the location of the displayed section within the complex. (C) End-on view of the density of the c ring. The inset shows the location of the , , , and subunits in relation to the c subunits. The helices of the c subunit are drawn as blue circles, the larger outer circles accounting for the larger side chains in the COOH-terminal helix. The outer diameter of the c ring is 55 Å (top) to 42 Å (equator) to 45 Å (bottom), and the inner diameter is 27 Å (top) to 17 Å (equator) to 22 Å (bottom). The dimensions exclude consideration of unresolved regions of density, including amino acid side chains and detergent or lipid molecules. The two regions of density near subunit 10 are not extensive and are likely to be noise.

Fig. 3. Stereo view of the crystal packing of the yeast F[1]c[10] complex. A 45 Å thick section through the crystal perpendicular to the crystallographic y axis is shown. The electron density is contoured at 1.2 . The red lines mark the x and z axes of the crystal lattice. All figures were prepared with the program MAIN (72).

Figure 3 Phosphate-binding site in the [E]-subunit of the yF[1]II complex. (A) Electron density of the final 2F[o]-F[c] map for the phosphate-binding site (contoured at 1.3 ). The electron density is shown only for a radius about the phosphate to simplify the image. (B) Side chains that contribute to phosphate binding. Possible ionic interactions are shown as dotted lines, with distances in Å. (C) Superposition of the phosphate-binding region of yF[1]I (green) on that of yF[1]II (blue). (D) Superposition of the phosphate-binding region of the empty subunit of bovine F[1] (pink) on yF[1]II (blue). The bovine residue numbering is used in this image.
Figure 5.
Figure 5 Relative movement of the phosphate molecule during the catalytic cycle. The predicted path of the phosphate molecule during catalysis is marked by the position of phosphate (or sulfate) in the [E]-subunits of the yF[1]II complex (blue), the bovine AlF[4]^-:ADP-inhibited structure (Menz et al, 2001) (yellow), and the -phosphate of AMPPNP bound to the [DP]-subunit of the yF[1]I complex (salmon). The structures were superimposed using the P-loop and neighboring catalytic residues ( 151–177, 330–336). The -carbon trace of the P-loop of all three enzymes is shown along with the bound nucleotide and phosphate (or sulfate) of yF[1]II (yellow). The inset shows just the movement of the phosphate relative to the nucleotide. The phosphate bound to [E] (blue) moves to the position in the AlF[4]^-:ADP-inhibited state (yellow) and ends as the -phosphate of ATP in the DP site (as colored). Also shown is the movement of Arg375 in the same path. The distances between the atoms are shown in Å.

Electron density at the catalytic sites of yeast F[1] ATPase in the absence of nucleotides. In each panel, the 2F[o] - F[c] map is shown (contoured at 1 σ) with the position of the nucleotide modeled from the ground state structure. The inset plots show the region where the nucleotide would bind and corresponding electron density. The main chain is represented as a ribbon in red and blue for the α and β subunits, respectively. The side chains of selected residues important for substrate binding and catalysis are shown. A, α[DP]/β[DP] site; B, α[TP]/β[TP] site; C, a noncatalytic (NC) site, all for Complex I. D, the phosphate-binding site in the α[E]/β[E] site of Complex II.

Figure 1.
Fig. 1. Structure of the I. tartaricus c[11] ring in ribbon representation. Subunits are shown in different colors. (A) View perpendicular to the membrane from the cytoplasmic side. Two subunits are labeled. (B) Side view. The blue spheres represent the bound Na^+ ions. Detergent molecules inside the ring are shown with red and gray spheres for clarity. The membrane is indicated as a gray shaded bar (width, 35 Å). The images were created with PyMOL (36).

Fig. 2. Section of the c ring showing the interface between the N-terminal and two C-terminal helices with those side chains discussed in the text. This three-helix bundle represents a functional unit responsible for Na^+ binding and allowing access of the ion to the binding site. The view is normal to the external surface of the c ring with the ring axis approximately vertical. The color coding of the subunits is the same as in Fig. 1A.
