| Type: | Family | Name: | LytTR stand-alone protein |
| Description: | Members of this group are stand-alone forms of the LytTR DNA-binding domain []. One of them is BlpS from Streptococcus pneumoniae. BlpS is encoded together with the components of the two-component system Blp, which also contains another LytTR-containing protein, the response regulator BlpR []. The Blp system is closely related to quorum-sensing systems regulating cell density-dependent phenotypes, such as the development of genetic competence or the production of antimicrobial peptides in lactic acid bacteria, and is a peptide-sensing system that controls the blpregulon. The blpregulon is composed of genes for regulation, synthesis, export, and processing of Blps (bacteriocin-like peptides) []. The exact function of BlpS is not clear. | Short Name: | LyTR_stand-alone |
