Phylogenetic tree of P. carnosa cytochrome P450 proteins (P450ome). Phylogenetic analyses were conducted in MEGA4 using the UPGMA method [75]. A total of 210 P450s (≥ 330 amino acids length) were grouped under ten existing clans and one unassigned clan (UA), with clans shown in different colors. P450 members that were upregulated in wood degrading cultures [10] are indicated with asterisks and are listed in Additional file 1: Table S15.
