Figure 2. Schematic drawing of a control apparatus. A laser of frequency coi is focused by lens L into a cell containing a tripling medium such as Hg vapor. Mirrors Ml and M2 are mounted inside a phase tuning cell (not shown) containing a refractive medium such as H2. The folded mirror geometry produces a pair of elliptical astigmatic foci, one of which overlaps the molecular beam (MB) at a distance zm from the beam axis.

When s-MDH is viewed down the dyad, as shown in Fig. 1, the first half of the polypeptide chain (ySA to ySF) is folded into a reasonably defined region. The second half of the molecule ( 2F to H) comprises the remaining part of the molecule. It should be emphasized that the distribution of atoms is continuous there is no visible bilobal structure as has been seen in other enzymes (65). The first six segments of the extended chain (pA to pF) form a twisted region of parallel sheet structure. The schematic drawing in Fig. 1 does not show this twist. The amino terminal part of the sheet (/3A, pB, and / C) is on the surface of the...

Basically, all mitochondria consist of two membranes which surround and enclose an inner compartment containing the mitochondrial matrix. The outer membrane is usually smooth in surface contour, whereas the inner membrane is folded into a series of lamellae, the cristae. The regions of the inner membrane between the cristae are designated collectively as the inner boundary membrane. The space between the outer and inner membranes, known as the inter membrane space, is continuous with the space bounded by the membranes of the cristae. Figure 1 shows a schematic drawing of a mitochondrion.

The X-ray crystal structure of MMOH from M. capsulatus (Bath) has been determined by Lippard et al at 2.2 A resolution [52, 53]. The X-ray diffraction data were collected at 4 The enzyme is a relatively flat molecule with approximate dimensions 60 x 100 x 200 A. The arrangement of the subunits is similar to the schematic drawing in Scheme 1. The two a-subunits contact one another and so do two P-subunits with more extensive contacts. The y-subunit lies on the outer edges of the molecule at the interface of the a-and p-subunit. The two apy protomers are related by a non-crystallographic two fold symmetry and form a heart-shaped molecule. There is a large canyon at the interface between the two aPy protomers. The secondary structure of the three subunits is primarily helical, with one small region of p-structure in the a-subunit. The a-subunit involves 18 helices and two P-hairpin motifs. The P-subunit has 12 helices. The y-...

Figure 2 shows a schematic drawing of the polypeptide chain folding of subunit M subunit L is folded very similarly. Structurally similar segments in both subunits include the transmembrane helices (labeled A, B, C, D, E) and a large fraction of the polypeptide chains connecting them. In total, 216 a-carbons...
