Identification and characterization of two Alcaligenes eutrophus gene loci relevant to the poly(beta-hydroxybutyric acid)-leaky phenotype which exhibit homology to ptsH and ptsI of Escherichia coli.


From genomic libraries of Alcaligenes eutrophus H16 in lambda L47 and in pVK100, we cloned DNA fragments which restored the wild-type phenotype to poly(beta-hydroxybutyric acid) (PHB)-leaky mutants derived from strains H16 and JMP222. The nucleotide sequence analysis of a 4.5-kb region of one of these fragments revealed two adjacent open reading frames (ORF… (More)
