Patent ID: 7416870

Claim:
A method of modifying a biological molecule by formation of a C—O bond comprising the step of contacting a biological molecule with a polypeptide selected from the group consisting of: (a) a polypeptide comprising the amino acid sequence set forth in SEQ ID NO: 3; (b) a polypeptide encoded by a nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO: 2; and (c) a polypeptide encoded by a nucleic acid that specifically hybridizes to SEQ ID NO: 2 under wash conditions of at least as stringent as 0.2×SSC wash at 65° C. for 15 minutes and which catalyzes C—O bond formation; wherein said biological molecule is a substrate for said polypeptide, and whereby said polypeptide modifies the biological molecule by formation of a C—O bond.
