Patent ID: 7199230

Claim:
An isolated nucleic acid selected from the group consisting of: (a) nucleic acid according to SEQ ID NO: 2 encoding preduramycin; (b) a nucleic acid according to SEQ ID NO: 4 encoding produramycin; (c) nucleic acids that are at least 95 percent identical in sequence to nucleic acids of (a) or (b) above and which encode said preduramycin or produramycin; (d) nucleic acids that differ from the nucleic acids of (a), (b), or (c) above due to the degeneracy of the genetic code, and which encode a preduramycin encoded by a nucleic acid of (a),(b), or (c) above, and wherein the preduramycin and produramycin are precursors of duramycin, which is an antibiotic.
