Crystal structures of the effector-binding domain of repressor Central glycolytic gene Regulator from Bacillus subtilis reveal ligand-induced structural changes upon binding of several glycolytic intermediates.

Expression of genes in the gapA operon encoding five enzymes for triose phosphate interconversion in Bacillus subtilis is negatively regulated by the Central glycolytic genes Regulator (CggR). CggR belongs to the large SorC/DeoR family of prokaryotic transcriptional regulators, characterized by an N-terminal DNA-binding domain and a large C-terminal effector-binding domain. When no glucose is present in growth media, CggR binds to its target DNA sequence and blocks the transcription of genes in the gapA operon.

Crystal structure and putative function of small Toprim domain-containing protein from Bacillus stearothermophilus.

The crystal structure of the Midwest Center for Structural Genomics target APC35832, a 14.7-kDa cytosolic protein from Bacillus stearothermophilus, has been determined at 1.3 A resolution by the single anomalous diffraction method from a mercury soaked crystal.
