This gene is a member of the following regulons
CcpA regulon, DegU regulon, SinR regulon, TnrA regulon
The DegU regulon
The gene
Basic information
- Locus tag: BSU35490
Phenotypes of a mutant
- defect in biofilm formation PubMed, this can be suppressed by DegU-independent expression of BslA PubMed
- the mutation suppresses the mucoid phenotype of motA or motB mutants due to reduced expression of the capB-capC-capA-capE operon PubMed
Database entries
- BsubCyc: BSU35490
- DBTBS entry: [1]
- SubtiList entry: [2]
Additional information
The protein
Basic information/ Evolution
- Catalyzed reaction/ biological activity:
- transcription activator and repressor (see DegU regulon)
- DegU-P represses expression of the fla/che operon (flgB-flgC-fliE-fliF-fliG-fliH-fliI-fliJ-ylxF-fliK-flgD-flgE-fliL-fliM-fliY-cheY-fliZ-fliP-fliQ-fliR-flhB-flhA-flhF-flhG-cheB-cheA-cheW-cheC-cheD-sigD-swrB) in the absence of SwrA, and switches to an activator of the operon in the presence of SwrA PubMed
