Isolation, Purification, and Characterization of Mitochondria from Chlamydomonas reinhardtii.
Mitochondria were isolated from autotrophically grown Chlamydomonas reinhardtii cell-wall-less mutant CW 92. The cells were broken by vortexing with glass beads, and the mitochondria were collected by differential centrifugation and purified on a Percoll gradient. The isolated mitochondria oxidized malate, pyruvate, succinate, NADH, and [alpha]-ketoglutarate. Respiratory control was obtained wi...
متن کاملPurification and characterization of NAD-isocitrate dehydrogenase from chlamydomonas reinhardtii
NAD-isocitrate dehydrogenase (NAD-IDH) from the eukaryotic microalga Chlamydomonas reinhardtii was purified to electrophoretic homogeneity by successive chromatography steps on Phenyl-Sepharose, Blue-Sepharose, diethylaminoethyl-Sephacel, and Sephacryl S-300 (all Pharmacia Biotech). The 320-kD enzyme was found to be an octamer composed of 45-kD subunits. The presence of isocitrate plus Mn2+ pro...
متن کاملIsolation and characterization of mitochondrial DNA from Chlamydomonas reinhardtii.
Mitochondrial DNA (mtDNA) has been isolated from a mitochondrial pellet of Chlamydomonas reinhardtii. The mtDNA has a buoyant density of 1.706 g/ml in CsCl, a melting temperature of 87.9 degrees in standard saline citrate, and a nucleoside composition of 47.5% deoxyguanidine plus deoxycytidine with no odd nucleosides. Thermal denaturation and renaturation studies have shown that (i) mtDNA conta...
متن کاملPurification of Hydrogenase from Chlamydomonas reinhardtii.
A method is described which results in a 2750-fold purification of hydrogenase from Chlamydomonas reinhardtii, yielding a preparation which is approximately 40% pure. With a saturating amount of ferredoxin as the electron mediator, the specific activity of pure enzyme was calculated to be 1800 micromoles H(2) produced per milligram protein per minute. The molecular weight was determined to be 4...
متن کاملPurification and cDNA isolation of chloroplastic phosphoglycerate kinase from Chlamydomonas reinhardtii.
Chloroplastic phosphoglycerate kinase (PGK) was purified to homogeneity from a soluble fraction of chloroplasts of a cell-wall-deficient mutant strain of Chlamydomonas reinhardtii (cw-15) using ammonium sulfate fractionation, Reactive Blue-72 column chromatography, and native polyacrylamide gel electrophoresis. PGK activity was attributed to a single polypeptide with a molecular mass of 42 kD. ...
