Interaction of Rhus laccase with dioxygen and its reduction intermediates.
Reduction-oxidation of native Rhus vernicifem laccase produces specific long-lived spectral changes in the near UV and visible region. These can be attained 1) in aerobic reduction experiments, 2) from partially and fully reduced laccase molecules reacting with 0 2 , 3) by reacting peroxylaccase with 2 reduction eq, and 4) upon reoxidation of fully reduced laccase by 2 mol eq of HzOz. The spect...

The two steps of the titration of the Japanese-lacquer-tree (Rhus vernicifera) laccase with N3- [Morpurgo, Rotilio, Finazzi-Agrò & Mondovi (1974) Biochim. Biophys. Acta 336, 324-328; LuBien, Winkler, Thamann, Scott, Co, Hodgson & Solomon (1981) J. Am. Chem. Soc. 103, 7014-7016] were shown to be two distinct reactions, each involving one different portion of the native enzyme molecules. The diff...
متن کاملAnaerobic reactions of Rhus vernicifera laccase and its type-2 copper-depleted derivatives with hexacyanoferrate(II).
Anaerobic reactions of Rhus vernicifera laccase and its type-2 copper-depleted derivatives with hexacyanoferrate(II) were investigated by absorption and e.s.r. spectroscopy. When native laccase was treated with excess hexacyanoferrate(II), the type-1 and type-2 coppers were immediately reduced and the e.s.r. signal due to type-3 copper was transiently observed. After incubation, a novel e.s.r. ...
