Patent ID: 7335756

Claim:
An isolated cDNA molecule comprising a sequence selected from the group consisting of: (a) SEQ. ID. NO. 10 or encoding the amino acid sequence of SEQ. ID. NO. 11; (b) a polynucleotide of (a) wherein T can also be U: (c) a polynucleotide having a nucleic acid sequence which differs from any of the nucleic acid molecules of (a) to (c) in codon due to the degeneracy of the genetic code; (d) a polynucleotide that is a variant, of any one of the polynucleotides of (a) to (c); wherein said variant is at least 95% identical to SEQ ID NO:10 and encodes a polypeptide that retains the substrate specificity of the polypeptide comprising the amino acid sequence of SEQ ID NO:11 and (e) a polynucleotide that is a fragment of any one of the polynucleotides of (a) to (d), wherein said fragment encodes a polypeptide that retains the substrate specificity of the polypeptide comprising the amino acid sequence of SEQ ID NO:11.
