Improving Degradation of Polycyclic Aromatic Hydrocarbons by Laccase Fused with Hemoglobin and a Novel Strong Promoter Replacement.

Laccases catalyze a variety of electron-rich substrates by reducing O to HO, with O playing a vital role as the final electron acceptor in the reaction process. In the present study, a laccase gene, , was identified from through sequence-based screening. LacH5 was engineered for modification by fusion expression and promoter replacement.
