The shp/rgg loci used in this study.

aGroup number of the SHP-associated Rgg according to the classification described in Fleuchot et al.[21].bThe shp gene is followed by the Genbank id of the rgg genes.cThe shp genes are not annotated in Genbank but were identified using BactgeneSHOW [20], except for the shp gene associated with ster_1299, which is annotated ster_1298 in the genome of S. thermophilus strain LMD-9. Consequently, all the shp gene products are indicated with the term “SHP” followed by the number of the cognate rgg gene in Genbank. To unify the nomenclature, the ster_1298 gene product was renamed SHP1299.dThe sequences of the synthetic peptides used in this study are underlined.
