Basic information/ Evolution
- Catalyzed reaction/ biological activity:
- SlrR binds to and inhibits the activity of SlrA, SlrA indirectly stimulates the synthesis of SlrR by interacting with SinR. SlrR can bind to SinR and SinR directly represses the transcription of SlrR. SlrR indirectly derepresses its own gene. The heterocomplex of SlrR-SinR is a repressor of autolysin and motility genes and inhibits the repressor function of SinR. PubMed
