5-Aminolevulinate Synthesis in Permeabilized Filaments of the Blue-Green Alga Anabaena variabilis.
Filaments of the blue-green alga Anabaena variabilis permeabilized by dimethylsulfoxide (DMSO) produce increased amounts of 5-aminolevulinate in the presence of levulinic acid. The metabolic activity of the filaments remains unperturbed in the presence of up to 7.5% (v/v) DMSO. Studies utilizing DMSO-permeabilized filaments confirm that 5-aminolevulinate is synthesized preferably from glutamate...

متن کاملEffect of Monochromatic Light on Proton Efflux of the Blue-Green Alga Anabaena variabilis.
Light-induced proton efflux of Anabaena variabilis was found to be biphasic, the second phase being inhibited by the ATPase inhibitor nitrofen (2,4-dichloro-1-[4-nitrophenoxy]benzene). The first, fast phase was triggered by monochromatic light of 707 nanometers, whereas the second, slower phase was not. With 707 nanometers, light, respiratory O(2) uptake was inhibited. Using light composed of t...
متن کاملLipopolysaccharide containing L-acofriose in the filamentous blue-green alga Anabaena variabilis.
For the first time, an O-antigenic lipopolysaccharide (LPS) has been isolated from a filamentous blue-green alga (Anabaena variabilis). It was extractable with phenol-water, resulting in extraction of the bulk of the LPS into the phenol phase. The polysaccharide moiety of this LPS consists of l-rhamnose, its 3-O-methyl ether l-acofriose, d-mannose, d-glucose, and d-galactose. l-Glycero-d-mannoh...
متن کاملA Chlorophyll-Containing Cell Fraction from the Blue-Green Alga, Anabaena variabilis
Previous studies on the fine structure of blue-green algae including Anabaena variabilis (1, 2) revealed the presence of arrays of cytoplasmic membranes similar to those described in the photosynthetic apparatus of higher plants (3). This report is not a systematic studyof the morphology of A. variabilis, but a description of observa-tiorts made on the intact cell and one of its fractions. Evid...
