additional information
in the laboratory strain 168, the [gene|5D479874B43F521DB52EDC2C27CDE4967F22DE47|swrA] gene contains a frameshift mutation (insertion of an extra A in a stretch of eight As), thus the gene is annotated as [gene|0CEE58D799AF41634D161DBDF3D67EEFFF1C861E|swrAA/2] (corresponds to the small N-terminal part of the protein) and [gene|5D479874B43F521DB52EDC2C27CDE4967F22DE47|swrA] (corresponds to the large C-terminal part of the protein) [pubmed|15066026]
the mutation readily reverts giving rise to swarming behaviour [pubmed|15066026]
the [gene|5D479874B43F521DB52EDC2C27CDE4967F22DE47|swrA] gene is intact in wild type strains such as NCIB3610 [pubmed|15066026]
