CC -!- FUNCTION: Sigma factors are initiation factors that promote the
CC attachment of RNA polymerase to specific initiation sites and are then
CC released. This sigma factor is responsible for the expression of
CC sporulation specific genes in the mother cell.
CC -!- INTERACTION:
CC P12254; P26937: spoIVFB; NbExp=2; IntAct=EBI-15806052, EBI-15806037;
CC -!- DEVELOPMENTAL STAGE: DNA rearrangement occurs at the third hour of
CC sporulation. Selectively expressed in the mother cell chamber of
CC sporulating cells.
CC -!- MISCELLANEOUS: The spoIVCB gene is an incomplete structural gene that
CC is capable of encoding only the N-terminal half of sigma-K. The
CC remainder of sigma-K is specified by another gene, spoIIIC, that is
CC about 10 kb from spoIVCB on the chromosome. The intervening fragment,
CC called skin, is excised at an intermediate stage of sporulation thus
CC allowing a full coding gene to be produced.
CC -!- SIMILARITY: Belongs to the sigma-70 factor family. {ECO:0000305}.
