Photoactivated adenylyl cyclase controls phototaxis in the flagellate Euglena gracilis.
Euglena gracilis, a unicellular freshwater protist exhibits different photomovement responses, such as phototaxis (oriented movement toward or away from the light source) and photophobic (abrupt turn in response to a rapid increase [step-up] or decrease [step-down] in the light fluence rate) responses. Photoactivated adenylyl cyclase (PAC) has been isolated from whole-cell preparations and iden...
متن کاملExpression of nucleus-encoded genes for chloroplast proteins in the flagellate Euglena gracilis.
Reverse transcription PCRs (RT-PCRs), real-time RT-PCRs and microarrays containing 50-mer oligonucleotides representing nucleus-encoded genes for chloroplast proteins from Euglena gracilis were used to compare light- and dark-grown wild-type mRNA levels to those of light- and dark-grown E. gracilis stable white mutant strains W(gm)ZOflL, W₃BUL and W₁₀BSmL. The analyses revealed no light-depende...
متن کاملThe Relationship between Chlorophyll and the Carotenoids in the Algal Flagellate, Euglena
1. We have obtained an action spectrum for chlorophyll formation in Euglena gracilis. This action spectrum is similar to the absorption spectrum of protochlorophyll. However, efforts to isolate and identify this pigment have been unsuccessful. 2. Porphyrins have been extracted from both the normal and dark-adapted Euglena and a chlorophyll-free mutant. 3. The "action" spectra for chlorophyll an...
متن کاملThe Mitochondrion of Euglena gracilis.
In the presence of oxygen, Euglena gracilis mitochondria function much like mammalian mitochondria. Under anaerobiosis, E. gracilis mitochondria perform a malonyl-CoA independent synthesis of fatty acids leading to accumulation of wax esters, which serve as the sink for electrons stemming from glycolytic ATP synthesis and pyruvate oxidation. Some components (enzymes and cofactors) of Euglena's ...
متن کاملDna-dependent Rna Synthesis in Chloroplasts of Euglena Gracilis
Isolated chloroplasts of Euglena gracilis have been shown to be capable of incorporating amino acids into protein (2). This incorporation is inhibited by actinomycin D, a fact which suggests that the chloroplasts might be capable of DNAdependent RNA synthesis. Such RNA synthesis is also indicated in a recent report (6) showing inhibition of chlorophyll synthesis by actinomycin. In conjunction w...
