Abstract: The teachings provided herein are generally directed to a method of converting lignin-derived compounds to valuable aromatic chemicals using an enzymatic, bioconversion process. The teachings provide a selection of (i) host cells that are tolerant to the toxic compounds present in lignin fractions; (ii) polypeptides that can be used as enzymes in the bioconversion of the lignin fractions to the aromatic chemical products; (iii) polynucleotides that can be used to transform the host cells to express the selection of polypeptides as enzymes in the bioconversion of the lignin fractions; and (iv) the transformants that express the enzymes.
