Laccase 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 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,...
متن کاملEffect of gibberellic acid on germination capacity and emergence rate of Sycamore maple (Acer pseudoplatanus L.) seeds
Seedlots of sycamore maple (Acer pseudoplatanus L.) originating from three different provenance regions were collected in autumn 2012. The seed quality, namely vitality and germination rate, was assessed according to Czech conventions. There were four replications within each seedlot, i.e. twelve treatments altogether for each experimental variant. The effect of gibberellic acid on germination ...
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 کاملAcer pseudoplAtAnus L., Acer plAtAnoides L. and BetulA pendulA Roth. as bioindicatoRs of uRban poLLution in sofia
Acer pseudoplatanus L., Acer platanoides L. and Betula pendula Roth. have been studied under the urban pollution in Sofia during 3 years period. The aim of the study was, by statistical multifactorial analysis, to assess the value changes in morphological parameters of species under air pollution and potential for species usage as bioindicators in observed regions. The statistical analysis incl...
