Patent ID: 6929938

Claim:
An isolated nucleic acid molecule selected from the group consisting of: a) a nucleic acid molecule which encodes a polypeptide comprising the amino acid sequence of SEQ ID NO:2 b) a nucleic acid molecule which encodes a polypeptide consisting of a fragment of the amino acid sequence of SEQ ID NO:2, wherein the fragment comprises the transfer domain of 25501 (amino acid residues 280 to 411 of SEQ ID NO:2) and has methyltransferase activity; and c) a nucleic acid molecule which encodes a naturally occurring allelic variant of a polypeptide comprising the amino acid sequence of SEQ ID NO:2, wherein the nucleic acid molecule hybridizes to a nucleic acid molecule comprising SEQ ID NO: 1, 3, or a complement thereof, under conditions of 0.5M sodium phosphate, 7% SDS at 65° C., followed by one or more washes at 0.2×SSC, 1% SDS at 65° C. and the variant has methyltransferase activity.
