Abstract: | Lignin, the most abundant renewable source of aromatic carbon on earth, consists in a highly irregular three dimensional biopolymer
of oxygenated phenylpropanoid units. In natural environments, lignin is only degraded efficiently by some basidioamycetes
that secrete an array of enzymes for this purpose. Recent advances in our understanding of the mechanism of lignin breakdown
have revealed several features that make this process highly unique from a biochemical standpoint. This article summarizes
some of them. |
