摘要:
The isolation and characterization of the promoter regions of the genes which code for the pilinic subunits fim2, fim3 and fimx of Bordetella pertussis, are described, as well as the construction of vectors containing the regions, and microorganisms transformed by the vectors.The promoter regions, or nucleotide fragments thereof, are particularly useful for the regulable or non-regulable expression of genes which code for a protein of interest in a strain of Bordetella. The transformed Bordetella strains are particularly suitable for the development of an effective anti-pertussis vaccine.

The present invention relates to the construction of functional engineered peptide synthetases capable of displaying a correct activity and their use for the non-ribosomal production of modified peptides.
摘要:
The invention relates to a method for the identification of propane-oxidizing bacteria which is based on the identification of at least one fragment of the prmA gene encoding the alpha subunit of the propane monooxygenase enzyme and/or the prmD gene encoding an ancillary protein involved in the oxidation reaction of propane by gene amplification in the presence of pairs of primers selected in correspondence of homologous portions, deduced from the alignment of the prmA and prmD sequences.
