Protein 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 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...
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 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 کاملNucleotide sequence of a cDNA clone encoding an acidic laccase from sycamore maple (Acer pseudoplatanus L.).
Laccases (p-diphenol:O, oxidoreductase, EC 1.1 0.3.2) are m,embers of a highly conserved class of metalloenzymes, the ”blue” copper oxidases, which includes ascorbate oxidase and ceruloplasmin (Rydén and Hunt, 1993). First identified more than 100 years ago in extracts of sap from the Japanese lacquer tree (Rhus vernicifera), laccases have since been identified in fungi, insects, higher plants,...
