The gene
Basic information
- Locus tag: BSU35230
Phenotypes of a mutant
Database entries
- DBTBS entry: no entry
- SubtiList entry: [1]
Additional information
- This protein is functional in undomesticated strains of B.subtilis but not in laboratory strains, such as 168, because of a frameshift mutation. Therefore laboratory strains of B.subtilis are unable to swarm.
- The frameshift in strain 168 is caused by a single insertion of an adenine in the codon for Tyr-12 which leads to the premature truncation of the protein in residue 13. In addition, the C-terminal section of swrAA was predicted to be an ORF (yvzD) by the genome project.
- Correction of sfp, epsC, swrAA, and degQ as well as introduction of rapP from a plasmid present in NCIB3610 results in biofilm formation in B. subtilis 168 PubMed
