Rapid Degradation of Abnormal Proteins in Vacuoles from Acer pseudoplatanus L. Cells.
In Acer pseudoplatanus cells, the proteins synthesized in the presence of an amino acid analog ([(14)C]p-fluorophenylalanine), were degraded more rapidly than normal ones ([(14)C]phenylalanine as precursor). The degradation of an important part of these abnormal proteins occurred inside the vacuoles. The degradation process was not apparently associated to a specific proteolytic system but was ...
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 کاملExpression 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 کاملLaccase from Sycamore Maple (Acer pseudoplatanus) Polymerizes Monolignols.
Current understanding of the final oxidative steps leading to lignin deposition in trees and other higher plants is limited with respect to what enzymes are involved, where they are localized, how they are transported, and what factors regulate them. With the use of cell suspension cultures of sycamore maple (Acer pseudoplatanus), an in-depth study of laccase, one of the oxidative enzymes possi...
