The amino acid sequence of stellacyanin from the lacquer tree
Biochemical and Biophysical Research Communications, 1977Summary The complete amino acid sequence of stellacyanin, a blue copper-containing glycoprotein, is presented. The protein has been enzymatically cleaved by trypsin, chymotrypsin, and by the protease from the Staphylococcus aureus strain U8. Stellacyanin consists of a single polypeptide chain of 107 amino acid residues.

The state of copper in stellacyanin and laccase from the lacquer tree Rhus vernicifera
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 19701. 1. The blue protein (stellacyanin) and the laccase (p-diphenol:oxygen oxidoreductase, EC 1.10.3.2) obtained from the latex of the Japanese lacquer tree Rhus vernicifera have been studied by electron paramagnetic resonance (EPR) and optical spectroscopy. 2. 2.

Chemotaxonomic application of Py-GC/MS: Identification of lacquer trees
Journal of Analytical and Applied Pyrolysis, 2010Abstract The trees of the species Rhus vernicifera, Rhus succedanea and Melanorrhoea usitate grow in various regions of Asia and their sap is used, for thousands of years, as coating materials for the most varied kinds of objects. After drying, the sap of these trees forms a very hard and durable polymer, commonly known as oriental lacquer.

Some Properties of Laccase from the Latex of Lacquer Trees
Nature, 1940WE have previously shown1 that laccase, the oxidizing enzyme present in the latex of the Indo-Chinese lacquer tree (Rhus succedanea), is a copper-protein compound. Our purest preparation of this enzyme, which catalyses the oxidation of polyphenols and diamines, contained 0·154 per cent copper and 6·45 per cent nitrogen, corresponding to about 45 per ...

Chemical Modification of Lacquer Tree Paint Using Primary Amines
Bulletin of the Chemical Society of Japan, 2003Abstract An investigation was undertaken on a chemical modification of urushi paint using a small amount of primary amines as additives by taking advantage of their reactivity with urushiol, one of the main components of urushi liquid, at room temperature.

Primary structure of a Japanese lacquer tree laccase as a prototype enzyme of multicopper oxidases
Journal of Inorganic Biochemistry, 2002The cDNA library of the Japanese lacquer tree (Rhus vernicifera) was constructed by the reverse transcription of mRNA. A cDNA encoding laccase was amplified by PCR using primers based on the N-terminal amino acid sequences of the purified laccase and its peptide fragments formed by digestions with chymotrypsin and trypsin, and subcloned.

An EPR study on the conformation of the copper sites of Japanese lacquer-tree laccase
Journal of Inorganic Biochemistry, 1986Abstract At liquid nitrogen temperature, the electron paramagnetic resonance (EPR) spectrum of type 1 Cu, in the type 2 Cu depleted Japanese laccase, was modified in a similar way by addition of urea, azide, or by acidification to pH ⩽ 4.5. The same effect on the type 1 Cu spectrum was produced in the native enzyme by urea or azide.

Cytotoxicity of urushiols isolated from sap of Korean lacquer tree (Rhus vernicifera stokes)
Archives of Pharmacal Research, 1999Cytotoxicities of four urushiols, congeners isolated from the sap of Korean lacquer tree (Rhus vernicifera Stokes), to 29 human cancer cell lines originated from 9 organs were evaluated. Their values of 50% growth inhibition were below 4 microg/ml, and showed cell line specific cytotoxicity. The present result is the first report on the cytotoxicity of

Plastic Shape Material “Urushi-Nendo” Applying Lacquer Tree Paint
Bulletin of the Chemical Society of Japan, 2004Abstract A new material for use in shaping has been created using urushi (Japanese lacquer) as a matrix, with natural fibers, such as cellulose as a filler and a primary amine as an additive, to promote the lacquer curing reaction. The cured material is characterized by exhibiting a strength comparable to that of wood.
