Patent ID: 7419812

Claim:
An isolated polypeptide having the ability to convert phenazine-1-carboxylic acid to at least one 2-hydroxylated phenazine (PhzO activity), wherein the isolated polypeptide is encoded by a nucleic acid molecule selected from the group consisting of: (a) the nucleotide sequence as given in SEQ ID NO:1 from nucleotide 76 to nucleotide 1546 or from nucleotide 89 to nucleotide 1564; (b) a nucleotide sequence encoding a polypeptide comprising an amino acid sequence of SEQ ID NO:2; (c) a nucleic acid sequence having at least 95% nucleotide sequence identity with SEQ ID NO:1 from nucleotide 89 through nucleotide 1546; (d) a nucleic acid sequence encoding a polypeptide having an amino acid sequence which has at least 95% sequence identity with SEQ ID NO:2; and (e) a nucleic acid sequence which hybridizes under high stringency conditions comprising hybridization at 68°C. in a solution consisting of 5X SSPE, 1% SDS, 5X Denhardt's reagent and 100 μg/ml denatured salmon sperm DNA followed by washing in a solution comprising 0.2X SSC, 1% SDS, 65°C., 15-20 min, with a nucleic acid sequence complementary to the nucleotide sequence of SEQ ID NO:1 from nucleotide 89 through nucleotide 1564.
