Definitions
- ⁇ -Ketoglutarate can be produced from glutamate, which is present in large quantities in cheese curds, by oxidative deamination, according to the following reaction: L-glutamate + H2O + NAD (P) + ⁇ -> ⁇ -ketoglutarate + NH4 + + NAD (P) H.
- Stringent hybridization conditions for a given polynucleotide, can be identified by those skilled in the art depending on the size and base composition of the polynucleotide concerned, as well as the composition of the hybridization mixture (in particular pH and ionic strength). Generally, stringent conditions for a polynucleotide of size and sequence data are obtained by operating at a lower temperature of about 5 0 C to 10 ° C than the melting temperature (Tm) of the hybrid formed from a mixture of hybridization of identical composition, with this polynucleotide and its complement.
- Tm melting temperature
- polynucleotides of at least 20 bp, preferably at least 50 bp, and preferably at least 100 bp will be favorably selected.
- particularly preferred polynucleotides are those derived from portions of the sequence SEQ ID NO: 1 which are not found in other regions of the L. lactis genome. Those skilled in the art can easily identify the relevant portions of the sequence SEQ ID NOrI by simple comparison of this sequence with the published complete sequence of L. lactis (AE005176, BOLOTIN et al., Genome Res., 11: 731-753, 2001).
- polynucleotides of 15 to 30 bp will advantageously be chosen.
- the present invention also encompasses any pair of primers allowing the specific amplification of a sequence encoding a GDH according to the invention, or a portion of said sequence, from the total DNA of the invention. a L. lactis strain containing said sequence.
- the subject of the present invention is also a process for obtaining a strain of L. lactis GDH positive, characterized in that it comprises the transformation of a strain of L. lactis GDH negative by a polynucleotide coding for a GDH compliant to the invention.
- the transformation of said negative GDH strain is carried out using the plasmid pGDH442.
- the strains containing the plasmid pGdh442 can therefore advantageously be used, in the context of the preparation of lactic starters in combination with strains having a proteolytic activity of casein, and capable of using lactose.
- the present invention will be better understood with the aid of the additional description which follows, which refers to examples illustrating the identification and cloning of a sequence coding for a L. lactis GDH, isolation and characterization. of the plasmid pGDH442 carrying this sequence, and the use of this sequence and this plasmid for obtaining and selecting positive GDH strains.
- the interruption of the gdh gene in the TIL 487 strain leads to a total loss of GDH activity, indicating that this gene is the only one responsible for the GDH activity of the TIL 442 strain.
