| pubmed-article:11092858 | pubmed:abstractText | The Spo0A protein of Bacillus subtilis is a DNA-binding protein that is required for the expression of genes involved in the initiation of sporulation. Spo0A binds directly to and both activates and represses transcription from the promoters of several genes required during the onset of endospore formation. The C-terminal 113 residues are known to contain the DNA-binding activity of Spo0A. Previous studies identified a region of the C-terminal half of Spo0A that is highly conserved among species of endospore-forming Bacillus and Clostridium and which encodes a putative helix-turn-helix DNA-binding domain. To test the functional significance of this region and determine if this motif is involved in DNA binding, we changed three conserved residues, S210, E213, and R214, to Gly and/or Ala by site-directed mutagenesis. We then isolated and analyzed the five substitution-containing Spo0A proteins for DNA binding and sporulation-specific gene activation. The S210A Spo0A mutant exhibited no change from wild-type binding, although it was defective in spoIIA and spoIIE promoter activation. In contrast, both the E213G and E213A Spo0A variants showed decreased binding and completely abolished transcriptional activation of spoIIA and spoIIE, while the R214G and R214A variants completely abolished both DNA binding and transcriptional activation. These data suggest that these conserved residues are important for transcriptional activation and that the E213 residue is involved in DNA binding. | lld:pubmed |
