Mechanisms of Lignin-Degrading Enzymes

摘要

Lignin is abundant in nature. It is a potentially valuable bioresource, but, because of itscomplex structure, it is difficult to degrade. However, enzymatic degradation of lignin is effective.Major lignin-degrading enzymes include laccases, lignin peroxidases, and manganese peroxidases.In this paper, the mechanisms of degradation of lignin by these three enzymes is reviewed, andsynergy between them is discussed.
