Intrinsic curvature properties of photosynthetic proteins in chromatophores.

In purple bacteria, photosynthesis is carried out on large indentations of the bacterial plasma membrane termed chromatophores. Acting as primitive organelles, chromatophores are densely packed with the membrane proteins necessary for photosynthesis, including light harvesting complexes LH1 and LH2, reaction center (RC), and cytochrome bc(1). The shape of chromatophores is primarily dependent o...

Intrinsic surface-drying properties of bioadhesive proteins.

Sessile marine mussels must "dry" underwater surfaces before adhering to them. Synthetic adhesives have yet to overcome this fundamental challenge. Previous studies of bioinspired adhesion have largely been performed under applied compressive forces, but such studies are poor predictors of the ability of an adhesive to spontaneously penetrate surface hydration layers. In a force-free approach t...

EFFECTS OF SALT AND IRRADIANCE STRESS ON PHOTOSYNTHETIC PIGMENTS AND PROTEINS IN DUNALIELLA SALINA TEODORESCO

The aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in Dunaliella salina Teod. The algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 M NaCl under three illumination regimens [4500 (control), 9000 and 11000 Lux]. The results showed that most electrophoresis protein bands were separa...

(Fermionic)Mass Meets (Intrinsic)Curvature

Using the notion of vacuum pairs we show how the (square of the) mass matrix of the fermions can be considered geometrically as curvature. This curvature together with the curvature of space-time, defines the total curvature of the Clifford module bundle representing a “free” fermion within the geometrical setup of spontaneously broken Yang-Mills-Higgs gauge theories. The geometrical frame disc...

Photoreduction of Ubiquinone and Photooxidiation of Phenazine Methosulfate by Chromatophores of Photosynthetic Bacteria and Bacteriochlorophyll.

A stimulation by phenazine methosulfate (PMS) of photophosphorylation with extracts of Rhodospirillum rubrum was first reported by Geller and Gregory,' who at the same time presented spectroscopic evidence that PMS was oxidized during the reaction. Jagendorf and Avron2 subsequently reported that PMS serves as a cofactor for cyclic photophosphorylation in chloroplasts, and considerable interest ...
