Publication Abstract from PubMed

The Obg nucleotide binding protein family has been implicated in stress response, chromosome partitioning, replication initiation, mycelium development, and sporulation. Obg proteins are among a large group of GTP binding proteins conserved from bacteria to man. Members of the family contain two equally and highly conserved domains, a C-terminal GTP binding domain and an N-terminal glycine-rich domain. Structural analysis of Bacillus subtilis Obg revealed respective domain architectures and how they are coupled through the putative switch elements of the C-terminal GTPase domain in apo and nucleotide-bound configurations. Biochemical analysis of bacterial and human Obg proteins combined with the structural observation of the ppGpp nucleotide within the Obg active sight suggest a potential role for ppGpp modulation of Obg function in B. subtilis.
