As a rather reactive trace gas, nitric oxide (NO) is formed from arginine by the enzyme nitric oxide synthase (NOS) in cells and tissues of humans and probably of higher animals, where NO plays an important role in signal transduction (Hausladen and Stamler, 1994). More recently it has been suggested that NOS activity and NO-mediated signal transfer also occur in plants (Delledonne et al.,1998;...
متن کاملPurification and characterization of cytochrome c6 from the unicellular green alga Scenedesmus obliquus.
Purification of a soluble cytochrome c6 from the unicellular green alga Scenedesmus obliquus by a simple and rapid method is described. The purification procedure includes ammonium sulfate precipitation and non-denaturating PAGE. The N-terminal sequence of the first 20 amino acids was determined and shows 85% similarity and 75% identity to the sequence of cytochrome c6 from the green alga Monor...
متن کاملEffect of Nano-Al2O3 on the Toxicity and Oxidative Stress of Copper towards Scenedesmus obliquus
Nano-Al₂O₃ has been widely used in various industries; unfortunately, it can be released into the aquatic environment. Although nano-Al₂O₃ is believed to be of low toxicity, it can interact with other pollutants in water, such as heavy metals. However, the interactions between nano-Al₂O₃ and heavy metals as well as the effect of nano-Al₂O₃ on the toxicity of the metals have been rarely investig...
متن کاملBioenergetic Strategy for the Biodegradation of p-Cresol by the Unicellular Green Alga Scenedesmus obliquus
Cultures from the unicellular green alga Scenedesmus obliquus biodegrade the toxic p-cresol (4-methylphenol) and use it as alternative carbon/energy source. The biodegradation procedure of p-cresol seems to be a two-step process. HPLC analyses indicate that the split of the methyl group (first step) that is possibly converted to methanol (increased methanol concentration in the growth medium), ...
متن کاملA novel type of Fe-hydrogenase in the green alga Scenedesmus obliquus is linked to the photosynthetic electron transport chain*,**
Hydrogen evolution is observed in the green alga Scenedesmus obliquus after a phase of anaerobic adaptation. In this study we report the biochemical and genetical characterization of a new type of Fe-hydrogenase (HydA) in this photosynthetic organism. The monomeric enzyme has a molecular mass of 44.5 kDa. The complete hydA cDNA of 2609 bp comprises an open reading frame encoding a polypeptide o...
