The expression and regulation of the gerBoperon has been examined using a lacZtranscriptional fusion and the transcriptional start defined. The gerBoperon is expressed during sporulation under the control of RNA polymerase containing the forespore-specific sigma factor, σG. This is a further homology to the gerAoperon, which is similarly regulated. It is predicted from the localization of expression and the encoded primary sequences that the GerB proteins are located at the inner spore membrane. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/13500872-140-11-3079
