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 directs the transcription of crystal
CC       protein genes, a sporulation-regulated event (By similarity).
CC       {ECO:0000250}.
CC   -!- PTM: Proteolytically cleaved in the N-terminus probably by a SpoIIGA
CC       homolog to yield the active peptide. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the sigma-70 factor family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAP11249.1; Type=Erroneous initiation; Evidence={ECO:0000305};
