Patent ID: 7435571

Claim:
An isolated DNA comprising (1) a nucleotide sequence that encodes decaprenyl diphosphate (DPP) synthase, said nucleotide sequence being selected from the group consisting of (a) the DNA sequence of SEQ ID NO: 16; (b) a DNA sequence which hybridizes under stringent conditions comprising hybridization in a buffer of 40% formamide, 1 M NaCl, 1% sodium dodecyl sulfate (SDS) at 37° C. and at least one wash in 0.2×SSC at a temperature of 60° C. for 20 minutes, to the full length complementary strand of SEQ ID NO: 16, and encodes a polypeptide having the activity of DPP synthase; and (c) a DNA sequence which is at least 90% identical to a DNA which codes for the polypeptide of SEQ ID NO: 17, said polypeptide having DPP synthase activity; or (2) a nucleotide sequence that encodes 4-hydroxybenzoate polyprenyltransferase, said nucleotide sequence being selected from the group consisting of: (a′) the DNA sequence of SEQ ID NO: 23; (b′) a DNA sequence which hybridizes under stringent conditions comprising hybridization in a buffer of 40% formamide, 1 M NaCl, 1% sodium dodecyl sulfate (SDS) at 37° C. and at least one wash in 0.2×SSC at a temperature of 60° C. for 20 minutes, to the full length complementary strand of SEQ ID NO: 23, and encodes a polypeptide having the activity of 4-hydroxybenzoate polyprenyltransferase; and (c′) a DNA sequence which is at least 90% identical to a DNA which codes for the polypeptide of SEQ ID NO: 24, said polypeptide having 4-hydroxybenzoate polyprenyltransferase activity.
