  • DNA sequence useful for the production of polyhydroxyalkanoates
    Patent number: 5750848
    Abstract: A genomic fragment harboring the gene phaG was cloned by phenotypic complementation of Pseudomonas putida KT2440 mutants, defective in the polyhydroxyalkanoic acid (PHA) synthesis via de novo fatty acid biosynthesis but not affected in PHA biosynthesis via fatty acid .beta.-oxidation. The 885-bp phaG gene encodes a protein of 295 amino acids with a molecular weight of 33,876 Da. The transcriptional induction of phaG could be observed under conditions of PHA synthesis via de novo fatty acid biosynthesis whereas no induction was detected under conditions which favor PHA synthesis via fatty acid degradation by .beta.-oxidation. The phaG gene is useful for the production of PHAs in bacteria and plants.
    Type: Grant
