Degradation of Paramylon by Euglena gracilis
The Journal of Protozoology, 1968SYNOPSIS. Protozoa of the order Euglenida contain a polysaccharide storage product, paramylon, composed of 1, 3‐linked glucose molecules arranged into an extremely resistant granule. An enzyme was purified from the soluble phase of Euglena gracilis which would degrade this polysaccharide to single glucose residues, providing the integrity of the ...

Fatty acid synthetases from Euglena gracilis
Archives of Biochemistry and Biophysics, 1971Abstract Fatty acid synthetases catalyzing the TPNH-dependent incorporation of acetyl-CoA and malonyl-CoA into long-chain fatty acids have been isolated from both etiolated and green cells of Euglena gracilis , strain Z. Conditions for growing the phytoflagellate determine the type of enzyme activity. Synthetase isolated from dark-grown Euglena is

Laminarase of Euglena gracilis
Science, 1960An enzyme in extracts of the protistan Euglena gracilis splits the polysaccharide laminarin (β-1:3-glucosan). Its optimal p H is 5.0, and it is activated by Mn ++ ions.

Functional Conservation of Calreticulin in Euglena gracilis
Journal of Eukaryotic Microbiology, 1998Calreticulin is the major high capacity, low affinity Ca2+ binding protein localized within the endoplasmic reticulum. It functions as a reservoir for triggered release of Ca2+ by the endoplasmic reticulum and is thus integral to eukaryotic signal transduction pathways involving Ca2+ as a second messenger.

Euglena Gracilis Case: A Real Biosensor
2003For over 100 years, a major object of photobiological studies has been the unicellular flagellate, Euglena gracilis, an organism well suited for such investigations by its special complement of organelles that may be considered an ancient, yet complete “visual” system.

Occurrence of norspermine in Euglena gracilis
Biochemical and Biophysical Research Communications, 1978Summary The tetraamine occurring in Euglena gracilis , previously believed to be spermine, is shown to be norspermine [N, N′-bis (3-aminopropyl)-1,3-diaminopropane]. Proof of identity was established by HPLC, HPCC and mass spectrometric investigations.

Ribosomal RNA cistrons in Euglena gracilis
Journal of Molecular Biology, 1973Abstract Euglena gracilis chloroplasts contain about 12 fg DNA of average density 1.686 g cm −3 and 1.7 pg RNA. The large (1.1 × 10 6 mol. wt) and small (0.56 × 10 6 mol. wt) ribosomal RNA components are coded for by separate cistrons, both of which band at a density of 1.696 g cm −3 in a CsCl gradient. About 6% of the chloroplast DNA codes for

Biosynthesis of Phosphatidylcholine in Euglena gracilis*†
The Journal of Protozoology, 1966SYNOPSIS. Extracts of Euglena gracilis carry out a very rapid but limited synthesis of phosphatidylcholine when S‐adenosylmethionine or ATP and methionine are supplied. Cytidinediphosphocholine apparently is not utilized. Qualitatively the same results are obtained whether the cells are light‐ or dark‐grown.

Gravitaxis and graviperception in euglena gracilis
Advances in Space Research, 1998Gravitactic orientation in the flagellate Euglena gracilis is mediated by an active physiological receptor rather than a passive alignment of the cells. During a recent space flight on the American shuttle Columbia the cells were subjected to different accelerations between 0 and 1.5 x g and tracked by computerized real-time image analysis.

Phosphatidyl choline species in Euglena gracilis
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1972Abstract 1. 1. The fatty acid composition of the phosphatidyl cholines and the phosphatidyl ethanolamines from cultures of Euglena gracilis grown in the light was determined and compared to that obtained from cultures grown in the dark. 2. 2.
