Insertional mutagenesis was used to isolate clones from Streptococcus thermophilus CNRZ368 that were modified in their abilities to tolerate oxidative stress. During this process, two menadione-sensitive clones (6G4 and 18C3) were found to display ab

International audience; In Streptococcus thermophilus, the locus rggC contains a frameshift mutation and thus consists of two open reading frames (ORFs), rggC 1 and rggC 2 , which encode proteins exhibiting similarity with the Rgg transcriptional reg

To better understand the defense mechanism of Streptococcus thermophilus against superoxide stress, molecular analysis of 10 menadione-sensitive mutants, obtained by insertional mutagenesis, was undertaken. This analysis allowed the identification of

The proteins RodA and PBP2b are implicated in the control of the ovoid-shape of Streptococcus thermophilus CNRZ368 and play a role in cells defence against superoxide radicals

International audience; A 32.5kb variable locus of the Streptococcus thermophilus CNRZ368 chromosome, the eps locus, contains 25 ORF and seven insertion sequences (IS). The putative products of 17 ORF are related to proteins involved in the synthesis
