Classification: CPC C | IPC C

Claim 0:
1. A recombinant polynucleotide comprising:
a LAC polynucleotide encoding a laccase (LAC) polypeptide capable of polymerizing caffeyl alcohol, the LAC polynucleotide encoding a polypeptide having a peptide sequence that is 100% identical to LAC8 from Cleome hassleriana (ChLAC8) having SEQ ID NO: 3, or is a variant thereof that is at least 99% identical to SEQ ID NO:3, and having a glutamine residue in an active site position of the polypeptide configured to be in substantial proximity to interact with a 3 hydroxyl group of a caffeyl alcohol bound in an active site of the polypeptide;
and at least one heterologous polynucleotide sequence operatively linked to the LAC polynucleotide.
