Patent ID: 8361771

Claim:
An isolated polynucleotide encoding a DNA methyltransferase selected from: (a) a polynucleotide encoding a polypeptide comprising an amino acid sequence having at least 95% sequence identity with amino acids 1 to 337 of SEQ ID NO: 2; (b) a polynucleotide comprising a nucleotide sequence having at least 95% sequence identity with nucleotides 1 to 1011 of SEQ ID NO: 1; and (c) a polynucleotide that hybridizes under high stringency conditions with nucleotides 1 to 1011 of SEQ ID NO: 1 or its full-length complementary strand wherein said high stringency conditions are hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 μg/ml sheared and denatured salmon sperm DNA, and 50% formamide, and washed three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C.
