Abstract
The Bacillus megaterium gene coding for small, acid-soluble spore protein (SASP) B was cloned and its nucleotide sequence was determined. The amino acid sequence predicted from the DNA sequence was identical to that determined previously for SASP B, with the exception of the amino-terminal methionine predicted from the gene sequence which is presumably removed posttranslationally and an asparagine residue predicted at position 21 which was originally identified as an aspartate residue. The mRNA encoded by the SASP B gene is synthesized for only a discrete period midway in sporulation, in parallel with mRNAs coding for other SASPs. The small size of the SASP B mRNA (365 nucleotides) indicated that the mRNA is monocistronic. The SASP B gene itself hybridized strongly to only one band in Southern blots of restriction enzyme digests of B. megaterium DNA, suggesting that the SASP B gene is not a member of a highly conserved multigene family, as is the case for other SASP genes.
