Abstract

Sporulation in Bacillus subtilis is initiated by activation of a specific transcription factor, sigmaF, which is controlled by a network of interactions amongst three proteins, SpoIIAA (AA), SpoIIAB (AB) and SpoIIE (IIE), and ATP and ADP. A detailed model of this network has recently been described. The structure of AA is known, but not those of AB or IIE. We propose NMR studies to identify the residues of AB involved in the various interactions, fluorescence experiments to confirm a postulated change in structure in AB, mutagenesis of AB to find variants with altered binding properties, the crystallisation of IIE and its fragments, and structural studies of AA in it phosphorylated form. Mathematical modelling of the network is also proposed.
