Expression of Amyloplast and Chloroplast DNA in Suspension-Cultured Cells of Sycamore (Acer pseudoplatanus L.).
Green mutant cells of sycamore (Acer pseudoplatanus L.), which had been selected by mutagenic treatment of the white wild type, grow photoheterotrophically in auxin-depleted culture medium. In contrast to the wild-type cells, mutant cells exhibit photosynthetic O(2)-evolution activity during their growth coincident with increases of (a) chlorophyll, (b) protein, and (c) ribulose-1,5-bisphosphat...
متن کاملExcretion of laccase by sycamore (Acer pseudoplatanus L.) cells. Purification and properties of the enzyme.
A laccase-type polyphenol oxidase is excreted by sycamore cells (Acer pseudoplatanus L.) cells. The enzyme has been purified by classical purification techniques. It is a blue copper protein of Mr 97 000, containing 45% carbohydrate and 0.24% copper. This protein consists of one single unit and the copper content corresponds to four copper atoms per protein molecule. The specific activity of th...
متن کاملProtein Phosphorylation in Amyloplasts Isolated from Suspension-Cultured Cells of Sycamore (Acer pseudoplatanus L.).
Highly purified amyloplasts were isolated from cultured cells of sycamore (Acer pseudoplatanus L.). Incubation of amyloplasts with [gamma-(32)P]-ATP resulted in the labeling of more than ten polypeptides. Pulsechase experiments showed the reversibility of the process with some but not all of the polypeptides. The phosphorylation reaction of one polypeptide, M(r) 100, was shown to be calcium dep...
متن کاملMitochondria of Isolated Plant Cells (Acer pseudoplatanus L.): II. Copper Deficiency Effects on Cytochrome C Oxidase and Oxygen Uptake.
The effects of copper deficiency on cell culture growth, cell respiration, mitochondrial oxidative properties, and electron transport chain have been studied with suspension-cultured sycamore cells (Acer pseudoplatanus L.). Within the range of the copper concentration studied (0.1-25 mug/1 of culture medium), the mean rate of cell division is independent of copper concentration. An initial copp...
متن کاملCharacterization and Intraorganellar Distribution of Protein Kinases in Amyloplasts Isolated from Cultured Cells of Sycamore (Acer pseudoplatanus L.).
Incubation of amyloplasts isolated from cultured cells of sycamore (Acer pseudoplatanus L.) with [gamma-(32)P]ATP resulted in the rapid phosphorylation (half-time of 40 seconds at 25 degrees Celcius) of organellar polypeptides. The preferred substrate for amyloplast protein kinases was Mg(2+). ATP, and recovery of only [(32)P]serine after partial acid hydrolysis indicated the predominance of pr...
