Lumenal gating mechanism revealed in calcium pump crystal structures with phosphate analogues.
C.Toyoshima, H.Nomura, T.Tsuda.
P-type ion transporting ATPases are ATP-powered ion pumps that establish ion concentration gradients across biological membranes. Transfer of bound cations to the lumenal or extracellular side occurs while the ATPase is phosphorylated. Here we report at 2.3 A resolution the structure of the calcium-ATPase of skeletal muscle sarcoplasmic reticulum, a representative P-type ATPase that is crystallized in the absence of Ca2+ but in the presence of magnesium fluoride, a stable phosphate analogue. This and other crystal structures determined previously provide atomic models for all four principal states in the reaction cycle. These structures show that the three cytoplasmic domains rearrange to move six out of ten transmembrane helices, thereby changing the affinity of the Ca2+-binding sites and the gating of the ion pathway. Release of ADP triggers the opening of the lumenal gate and release of phosphate its closure, effected mainly through movement of the A-domain, the actuator of transmembrane gates.

Figure 5.
Figure 5: Details of the phosphorylation site in E2 [glyph.gif]MgF[4]^2-. In the enlarged view (b), the atomic model of aspartylphosphate taken unchanged from a related protein CheY (PDB accession code 1QMP)29 is incorporated. The blue net in a shows an omit annealed Fo -Fc map (at 5 ; temperature factor also refined) at 2.3 resolution. Small spheres represent water molecules (red) and Mg2+ (green). MgF[4]^2- is shown in ball-and-stick representation. Large yellow arrow indicates the expected water attack to the aspartylphosphate (P-D351). Conserved sequence motifs are shown in a. Broken lines in pink indicate likely hydrogen bonds, and those in light green coordinations of Mg2+.

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 codes are shown on the right.
