    Polyadenylated mRNA for the light-harvesting chlorophyll a/b protein (1980)
    Springer
    Planta 148 (1980), S. 444-447 
    Details
    ISSN: 1432-2048
    Keywords: Cell cultures ; Chlorophyll protein ; Photosynthesis (light harvesting) ; Poly(A)RNA ; Thylakoid membranes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract In thylakoid membranes isolated from green plants of parsley, pea, and barley, the light-harvesting chlorophyll a/b protein complex (LHCP, mol. weight: 25,000), is a major constituent. Poly(A)RNA isolated from these species was translated in a wheat germ, cell-free system. The in vitro translation products were treated with antibodies raised against the LHCP. This treatment resulted in the precipitation of a precursor protein (mol. weight: 29,000). Poly(A)RNA was also prepared from a cell culture ofPetroselinum that does not develop chloroplasts upon illumination. This poly(A)RNA is capable of stimulating amino acid incorporation in the in vitro translation system, however, it does not direct the synthesis of LHCP.

    Kinetics of the appearance of mRNA for light-harvesting chlorophyll a/b protein in polysomes of barley (1980)

    Notes: Abstract Polysomes from dark-grown and illuminated barley seedlings were translated in cell-free systems. The translation products reacting with the antibody against the light-harvesting chlorophyll a/b protein (LHCP) were analyzed by polyacrylamide gel electrophoresis. It was found that, in addition to the precursor protein of LHCP, a product was obtained that co-migrated with the mature protein. Furthermore, the results show that the light-induced proly(A)RNA for LHCP is integrated into the polysomal complex without delay, indicating that the integration of LHCP into the membrane is controlled at a higher level of gene expression.

    Photoinitiated degradation of poly(diacetylene)s in solution by random chain scission (1984)
    New York : Wiley-Blackwell
    Die Makromolekulare Chemie 185 (1984), S. 1727-1737

    Notes: Poly(diacetylene)s dissolved in common organic solvents undergo random chain scission, if irradiated by UV-light. The pure polymers and their solutions are, however, stable, if they are photoirradiated within the main-absorption band of the polymer backbone. The usual triplet sensitizers, especially in the presence of oxygen, and radical donors such as 2,2′-azoisobutyronitrile (AIBN) enhance the rate of photodegradation. Suitable dyes are able to sensitize the chain-scission in the visible regions as well. Random chain scission occurs also in the dark, but only at temperatures above room temperature and is enhanced by the addition of radical-donors, e.g. AIBN. A mechanism of chain scission, induced by the attack of a radical to a multiple bond of the polyconjugated backbone of the polymer is proposed.

    Stress relaxation in fine fibrin films: Comparison of films prepared with thrombin and ancrod (1984)
    New York : Wiley-Blackwell
    Biopolymers 23 (1984), S. 2311-2323

    Topics: Chemistry and Pharmacology
    Notes: Measurements of stress relaxation in uniaxial extension have been made on fibrin film prepared from fine bovine fibrin clots (i.e., clots in which there is minimal lateral aggregation of protofibrils), both ligated and unligated, and polymerized with both thrombin and ancrod, plasticized with either aqueous buffer or glycerol. The stress 100 s after imposition of strain was approximately proportional to In λ, where λ is the stretch ratio. Ligated thrombin films showed comparatively little relaxation over a period of one day and almost complete recovery after release of stress. In unligated thrombin films, there was substantial relaxation in two stages, as previously observed for coarse films, and substantial irrecoverable deformation. The extent of relaxation and the proportion of strain that was irrecoverable increased with the magnitude of the strain. In ancrod films (unligated), there was much more relaxation (stress decaying by as much as a factor of 10) and much more irrecoverable deformation (about 70% of the initial deformation); these results did not depend on the magnitude of the strain. When an ancrod film was released after relaxation and submitted to a second stretch, the extent of the second relaxation was much less. These observations are discussed in relation to the structure of fine films and possible mechanisms for relaxation and irrecoverable deformation.
