Characterization of an Unusual LOV Domain Protein in the [alpha]-Proteobacterium Rhodobacter sphaeroides
Sep 01, 2009; ... ABSTRACT The facultatively prototrophic purple bacterium Rhodobacter sphaeroides 2.4.1 harbors a LOV (light, oxygen and voltage) domain protein, which shows a particular structure. LOV domains perceive blue light by a noncovalently bound flavin and transmit the signal to various coupled ...
Does the DNA Binding Mode of a Molecule Affect its Ability to Interact With Singlet Oxygen?
Sep 01, 2009; ... ABSTRACT Singlet oxygen is known to be a potent mutagenic agent and several biologically relevant molecules have been proposed to act as scavengers for this noxious species. However, numerous studies have been conducted in homogenous solution and the reactivity of singlet oxygen ...
Photochemistry and Thermal Decarboxylation of [alpha]-Phosphoryloxy-p-nitrophenylacetates
Sep 01, 2009; ... ABSTRACT α-Carboxy-4-nitrobenzyl phosphate 4 and its derived monomethyl phosphate ester 5 were synthesized and purified by anion-exchange chromatography. A grathent of LiCl was necessary for elution of the anion-exchange column to avoid unexpected thermal decarboxylation that ...
Dye-Surfactant Interaction: Modulation of Photophysics of an Ionic Styryl Dye
Sep 01, 2009; ... ABSTRACT The interesting modulation of multibond rotation-induced intramolecular charge transfer photophysics of 2-(4-(dimethylamino) sryryl)-1-methylpyridinium iodide in different micelles due to different contributions of twisted intramolecular charge transfer (TICT) and hydrogen ...
Introduction to the Symposium-in-Print on Photosynthesis
Nov 01, 2008; ... Photochemistry in nature drives an incredible range of signaling pathways. Blue-light receptors, based on flavin chromophores, are found in virtually all major groups of organisms save for animals. Phytochromes abound in green plants, algae, fungi and some bacteria. Retinylidene proteins are ...
