The gene

Basic information

• Locus tag: BSU03570

Phenotypes of a mutant

No swarming motility on B medium. PubMed

Database entries

• DBTBS entry: no entry

• SubtiList entry: [1]

Additional information

• This gene is a pseudogene in B. subtilis 168 due to a mutation that resulted in an internal frameshift. The second part of the pseudogene is sfp/2.
• 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
