Function

[SDA_BACSU] Mediates a developmental checkpoint inhibiting initiation of sporulation (by preventing phosphorylation of spo0A) in response to defects in the replication initiation machinery. Inhibits autophosphorylation of the histidine protein kinase KinA, forming a molecular barricade that prevents productive interaction between the ATP-binding site in the catalytic domain and the phosphorylatable His in the phosphotransfer domain of KinA. Probably also inhibits the activity of KinB, but has relatively little effect on KinC. Has at least one target in vivo in addition to KinA as sda does not require KinA to inhibit sporulation.^[1] ^[2]

Publication Abstract from PubMed

The crystal structure of the DNA-damage checkpoint inhibitor of sporulation, Sda, from Bacillus subtilis, has been solved by the MAD technique using selenomethionine-substituted protein. The structure closely resembles that previously solved by NMR, as well as the structure of a homologue from Geobacillus stearothermophilus solved in complex with the histidine kinase KinB. The structure contains three molecules in the asymmetric unit. The unusual trimeric arrangement, which lacks simple internal symmetry, appears to be preserved in solution based on an essentially ideal fit to previously acquired scattering data for Sda in solution. This interpretation contradicts previous findings that Sda was monomeric or dimeric in solution. This study demonstrates the difficulties that can be associated with the characterization of small proteins and the value of combining multiple biophysical techniques. It also emphasizes the importance of understanding the physical principles behind these techniques and therefore their limitations.
