Patent ID: 8410341

Claim:
An isolated nucleic acid molecule comprising a nucleotide sequence selected from the group consisting of: (a) the nucleotide sequence set forth in SEQ ID NO: 1; (b) the nucleotide sequence set forth in SEQ ID NO: 2; (c) a nucleotide sequence that encodes a polypeptide having the amino acid sequence set forth in SEQ ID NO: 3; (d) a nucleotide sequence that is at least 95% identical to the full length nucleotide sequences of (a), (b), or (c) and encodes an N-methylputrescine oxidase (MPO) enzyme; (e) a nucleotide sequence that hybridizes under high stringent conditions to the full length nucleotide sequences of (a), (b), (c), or (d) and encodes an MPO enzyme; and (f) a nucleotide sequence that differs from the nucleic acid sequence of (a) or (b) due to the degeneracy of the genetic code and encodes an MPO enzyme.
