Long stalk

The crystal structure of Cull has been resolved [21] and found to resemble a long stalk connecting two protein-interaction domains at either end of the stalk. 

The enzyme ATP synthase, formerly called F0FrATPase, makes most of the ATP, using ADP and inorganic phosphate, in mitochondria, eubacteria, and chloroplasts.91 The F0 component sits in the membrane and is connected to the Fj component, which is in the cytosol, by a 45-A-long stalk (the y subunit). The coupling of ATP synthesis to the flow of hydrogen ions across the membrane is done by the F0 part. The bovine F, complex is an assembly of five polypeptides, cr3, /33, y, 8, and e, of Mr 371 000. The three a and three /3 subunits are packed in a cylinder around the y, alternating a-/3-a-/3-a-/3.92... 

Features This slender, sparsely branched plant reaches a height of one to two feet. The stem leaves have two leaflets, with one margin-toothed terminal lobe. The root leaves are on long stalks with two small leaflets at the base. The yellow, erect flowers, with naked styles, appear between May and September. The root is short, hard and rough, with light brown rootlets. 

Features Stem and stalk soft and pithy. Thin, brittle, dark green leaves with long stalks and three obovate leaflets, about two inches long by one inch broad, entire... 

Features Stem long and creeping, rooting at joints, as the strawberry. Leaf stalks one to two inches long with five obovate leaflets, serrate, scattered hairs, veins prominent below. Flowers (June-September) bright yellow, five petals, solitary, on long stalks from stem as the leaves. 

Features Stem up to eighteen inches, slender, hairy, well-branched. Leaves opposite, oval-lanceolate, slightly serrate, nearly sessile root leaves stalked, ovoid, smooth at margins. Flowers dark purple, on long stalk, florets bunched together. 

Features Whole plant covered with silky hairs. Leaves rounded, about two inches across, nine blunt, serrate lobes, on long stalks. Greenish flowers, without petals, bloom in small clusters from forked stem. Astringent, saliva-drying taste. 

Features Stem nearly simple, reddish, furrowed, up to two feet high. Leaves radical, palmate, long-stalked, glossy green above, paler underneath, serrate, nearly three inches across. White, sessile flowers, blooming in June and July. Taste astringent, becoming acrid. 

Features This is, perhaps, best known of all wild plants, with its long-stalked, heart-shaped leaves, and delicate, characteristically-scented and coloured flowers. 

A well-known corn weed, the tall, slender stem, 2 to 4 high, has a dense coat of white hairs. The narrow, lanceshaped leaves, 4" to 5" in length, are produced in pairs and their stalkless bases meet around the stem. The large solitary flowers have very long stalks which issue from the axils of the leaves. They are 1.5" and 2" broad, with purple petals having pale streaks to the mouth of the tube. Sometimes, smaller flowers are produced in addition, which are entirely female, for the stamens are not devel... 

Let us first consider the structure of myosin. The results of electron microscopic studies of skeletal-muscle myosin show it to be a two-headed structure linked to a long stalk (Figure 34.2). As we saw in Chapter 33, limited proteolysis can be a powerful tool in probing the activity of large proteins. The treatment of myosin with trypsin and papain results in the formation of four fragments two SI fragments an S2 fragment, also called heavy... 

Both series are based on a very simple idea. Imagine arose on a long stalk. We are interested in the distance of the...
