Important note

In 168, the Skin element disrupts the sigK gene
A strain devoid of the Skin element (1A884) is available at the BGSC, PubMed
A strain devoid of PBSX prophage , SP-beta prophage and the Skin element (TF8A) as well as a strain devoid of all six prophages of the 168 genome (D6) is available in Jan Maarten van Dijl's lab PubMed
deletion of the skin element results in an increased rate of spontaneous germination due to lower expression of GerE PubMed
