• Efficient lignin depolymerization is unique to the wood decay basidiomycetes, collectively referred to as white rot fungi. Phanerochaete chrysosporium simultaneously degrades lignin cellulose, whereas the closely related species, Ceriporiopsis subvermispora, also depolymerizes lignin but may do so with relatively little cellulose degradation. To investigate the basis for selective ligninolysis, we conducted comparative genome analysis of C. subvermispora and P. chrysosporium. Genes encoding man-ganese peroxidase numbered 13 and five in C. subvermispora and P. chrysosporium, respectively. In addition, the C subvermispora genome contains at least seven genes predicted to encode laccases, whereas the P. chrysosporium genome contains none. We also observed expansion of the number of C subvermispora desaturase-encoding genes putatively involved m lipid metabolism. Microarray-based transcriptome analysis showed substantial up-regulation of severdesaturase and MnP genes in wood-containing medium. MS identified MnP proteins in C subvermispora culture filtrates, but none in P. chrysosporium cultures. These results support the importance of MnP and a lignin degradation mechanism whereby Cleavage of the dominant nonphenolic Structures ¡s mediated by lipid peroxidation products. Two C. subvermispora genes were predicted to encode peroxidases structurally Similar to P. Chrysosporium lignin peroxidase and, following heterologous expression in Escherichia coli, the enzymes were Shown to oxidize high redox potential Substrates, but not Mn²⁺. Apart from oxidative lignin degradation, we also examined cellulolytic and hemicellulolytic systems in both fungi. In summary, the C. subvermispora genetic inventory and expression patterns exhibit increased oxidoreductase potential and diminished celluloand lytic capability relative to P. chrysosporium.
