Rhus Vernicifera

Resonance-Raman spectra of Japanese-lacquer-tree (Rhus vernicifera) laccase, type-2-copper-depleted laccase and the latter form treated with H2O2 were measured in liquid and frozen solution, on excitation into the 600 nm absorption band. Significant changes in intensity and/or frequency of the bands lying in the 370-430 cm-1 region were observed on freezing, indicating local structural rearrangements taking place at the blue copper site. These findings corroborate previous suggestions based on e.p.r. measurements and redox data [Morpurgo, Calabrese, Desideri & Rotilio (1981) Biochem. J. 193, 639-642]. They show the strong dependence of the physical properties of blue copper centres on local symmetry. Some conclusions on the origin of the Raman bands are also drawn.

Pb2P2Se6 crystallizes in the monoclinic system, space group Pn (No. 13) with the lattice constantsa = 974.2 (4) pm. b = 766.2 (3) pm. c = 689.8 (3) pm, β=91.44(5)°.The title compound is isotypic to the homologous Pb2P2S6. In the structure there are discrete P2Se4-6 anions.Far infrared, infrared and Raman spectra of this compound have been recorded. The observed frequencies are assigned on the basis of P2Se4-6 units with C2h symmetry in the crystal. DTA-data have been determined and interpreted.
