Role of the sporulation protein BofA in regulating activation of the Bacillus subtilis developmental transcription factor sigmaK.

abstract：:The 2,647-bp nucleotide sequence of cryptic plasmid pTD1, isolated from the oral spirochete Treponema denticola, was determined. The sequence revealed two open reading frames, A and B, which encode polypeptides of 335 and 235 amino acids, respectively. Open reading frame A shows sequence similarity to genes that encod...
