The 9 A projection structure of cytochrome b6f complex determined by electron crystallography.
Thin three-dimensional crystals of the cytochrome b6 f complex from the unicellular algae Chlamydomonas reinhardtii have been grown by BioBeads-mediated detergent removal from a mixture of protein and lipid solubilized in Hecameg. Frozen-hydrated crystals, exhibiting p22121 plane group symmetry, were studied by electron crystallography and a projection map at 9 A resolution was calculated. The ...
متن کاملPrevention of Atherosclerosis Progression by 9-cis-β-Carotene Rich Alga Dunaliella in apoE-Deficient Mice
INTRODUCTION β-Carotene-rich diet has been shown to be inversely associated with the risk of coronary heart disease. However, clinical trials using synthetic all-trans-β-carotene failed to demonstrate a beneficial effect. We therefore sought to study the effect of natural source of β-carotene, the alga Dunaliella, containing both all-trans and 9-cis-β-carotene on atherosclerosis. In a previous ...
متن کاملFunctional characterization of the small regulatory subunit PetP from the cytochrome b6f complex in Thermosynechococcus elongatus.
The cyanobacterial cytochrome b(6)f complex is central for the coordination of photosynthetic and respiratory electron transport and also for the balance between linear and cyclic electron transport. The development of a purification strategy for a highly active dimeric b(6)f complex from the thermophilic cyanobacterium Thermosynechococcus elongatus BP-1 enabled characterization of the structur...

متن کامل9-cis β-Carotene Increased Cholesterol Efflux to HDL in Macrophages
Cholesterol efflux from macrophages is a key process in reverse cholesterol transport and, therefore, might inhibit atherogenesis. 9-cis-β-carotene (9-cis-βc) is a precursor for 9-cis-retinoic-acid (9-cis-RA), which regulates macrophage cholesterol efflux. Our objective was to assess whether 9-cis-βc increases macrophage cholesterol efflux and induces the expression of cholesterol transporters....
