^aEnzyme amino acid sequences (numbers in parentheses below are accession numbers) are the polyphenol oxidase from A. murorum (this paper), bilirubin oxidase from M. verrucaria (Q12737), and laccases from T. villosa (lcc1) (Q99044), Trametes versicolor (lcc4) (Q12719), P. ostreatus (pox2) (Q12739), Phlebia radiata (Q01679), A. bisporus (Q12542), N. crassa (P10574), M. thermophila (AR023901), S. thermophilum (AR007280), Botrytis cinerea (Q12570), Cryphonectria parasitica (Q03966), and A. nidulans (P17489). When neccessary, DNA sequences were translated into amino acid sequences.
