Autoreduction and aggregation of fungal laccase in solution phase: possible correlation with a resting form of laccase
(2006) In Biochimie 88(9). p.1275-1285- Abstract
- This paper reports results of a reexamination of some poorly understood peculiarities of laccases, an enzyme family which has been extensively studied in our laboratories as well as by others for some years. The issue that is reconsidered here is the previously proposed existence of ''active" and "resting" forms of laccases. The presence of fungal laccases with partly reduced active sites is demonstrated. Of further interest is that an aggregated state in solution, not to our knowledge previously noted for laccase, has been found by using small-angle X-ray scattering as well as thorough analysis of the results of several biochemical experiments. Under some conditions, this aggregated state may correlate with the resting form of the... (More)

Under some conditions, this aggregated state may correlate with the resting form of the laccases, although this resting form could have a broader significance. It was shown that Trametes ochracea laccase had some anomalous characteristics, which could be correlated with the high concentration of the "resting" enzyme. The mechanism of formation of resting laccase is suggested. Knowledge of the resting state is of importance for in vitro studies. Additionally, a suggestion about the possible regulatory role of this form in vivo is mentioned. (c) 2006 Elsevier SAS. All rights reserved. (Less)
