- R M mechanisms types I. II, and III
- BICKLE and KRUGER Microbiological Reviews, 57, pp. 434-450 (1993)
- the characteristics of the R / M mechanisms of types I and II are briefly recalled below:
- Preferred subfragments are those which are located in sequences encoding conserved regions between the HsdR subunits, between the HsdM subunits or between the HsdS subunits of the R / M type II-conforming mechanisms. invention.
- a host bacterium already comprising at least one sequence coding for an Abi mechanism and / or at least one sequence coding for an R / M type II mechanism, or to introduce to the times in the host bacterium, the sequence (s) coding for the Abi and / or R / M type II mechanism (s), and the sequence (s) coding for the subunit (s) ) HsdR, HsdM or HsdS.
- the hsdM type sequence obtained from the chromosomal DNA of the strain IL 1403, and the sequence of the corresponding polypeptide are respectively represented in the sequence list in the appendix under the numbers SEQ ID NO: 5 and SEQ ID NO: 6.
- the hsdR type sequence obtained from the plasmid derived from the strain of L. lactis ssp. lactis IL420, and the sequence of the corresponding polypeptide are respectively represented in the annexed sequence list under the numbers SEQ ID NO: 3 and SEQ ID NO: 4
- the hsdM type sequence obtained from the plasmid derived from the strain of L. lactis ssp. lactis IL420, and the sequence of the corresponding polypeptide are respectively represented in the sequence list in the appendix under the numbers SEQ ID NO: 7 and SEQ ID NO: 8.
- oligonucleotides are used as primers for PCR amplification (66/69 and 67/68 pairs) of 16 different strains of Lactococcus.
- Table II below shows the results obtained with phage c2 on the strain MG1363, chosen as a control, and the strain IL 1403.
- the HsdS subunits of the different resistance mechanisms do indeed have a different specificity: the mechanism carried by the chromosome of the IL 1430 strain is weakly effective against the phage bIL67, while on the other hand the HsdS subunits carried by the plasmids increase, to a greater or lesser degree, resistance to this phage.
- the HsdS subunits coded by the plasmids pIL7 and pIL261 can associate with the HsdR and HsdM subunits coded by the chromosome of IL1430 to reconstitute an R / M complex of the functional type.
