Channel structures, diagram

Framework and polyhedral figures were drawn using ATOMS V6.2 by Shape Software. Channel system diagrams were generated using the 3D drawing option at the IZA Structure Commission web site [4].

Figure 18.3 Protein crystals contain large channels and holes filled with solvent molecules, as shown in this diagram of the molecular packing in crystals of the enzyme glycolate oxidase. The subunits (colored disks) form octamers of molecular weight around 300 kDa, with a hole in the middle of each of about 15 A diameter. Between the molecules there are channels (white) of around 70 A diameter through the crystal.

The structure constants of the SU(3) group responsible for this transition are equal to zero /391 = /3i0i = /39s = /3108 = 0. It should be noted that the diagrams 2 and 3 do not contribute to the partial width of the 0 — con0 decay channel which is obvious also due to the hadronic flavor conservation principle. According to the expression (2),also the anomalous diagram (FIG.4.) does not contribute to the partial width of the 0 —> W7T° decay because... 

Finally the diagram with the intermediate oj meson (FIG. 5) does not contribute to the partial width of this decay channel also because of these structure constants.

Diagram of the structures involved in the stretch reflex arc. I is an inhibitory interneuron E indicates an excitatory presynaptic terminal la is a primary intrafusal afferent fiber Ca2+ denotes activator calcium stored in the sarcoplasmic reticulum of skeletal muscle RyR channels indicates the Ca2+ release channels. 

Figure 8-26 The structure of the 994-residue Ca2+-ATPase of the endoplasmic reticulum of rabbit muscle at 0.8-nm resolution. (A) Predicted topology diagram organized to correspond to the electron density map prepared by electron crystallography of frozen-hydrated tubular crystals. The number of amino acid residues in each connecting loop is marked. (B) The electron density map with the predicted structure embedded. The relationships of the helices in (B) to those in (A) are not unambiguous. The helices marked B, D, E, and F in (B) may form the Ca2+ channel. The large cytoplasmic loops, which are black in (A), were not fitted. From Zhang et al.553 Courtesy of David L. Stokes.

The filter bank is the deciding factor for the basic structure of a perceptual coding system. Figure 2.6 shows the basic block diagram of an static n-channel analysis/synthesis filter bank with downsampling by k. If k = n, it is called a filter bank with critical sampling. A number of basic parameters can be used to describe filter banks used for audio coding ... 

Schematic diagram of a cardiac muscle sarcomere, with sites of action of several drugs that alter contractility (numbered structures). Site 1 is Na+/K+ ATPase, the sodium pump. Site 2 is the sodium/calcium exchanger. Site 3 is the voltage-gated calcium channel. Site 4 is a calcium transporter that pumps calcium into the sarcoplasmic reticulum (SR). Site 5 is a calcium channel in the membrane of the SR that is triggered to release stored calcium by activator calcium. Site 6 is the actin-troponin-tropomyosin complex at which activator calcium brings about the contractile interaction of actin and myosin.
