Neighbor joining tree of multicopper oxidase amino acid sequences. The A. niger MCOs (in dark blue) are distributed amongst the ascomycete laccases, fungal pigment MCOs, fungal ferroxidases and ferroxidases/laccases subfamilies. The phylogenetic tree was constructed with MEGA4, using the Poisson correction model, pairwise deletion and 500 replicates. Only values ≥ 50% are shown.
