'''Structure of the Obg GTP-binding protein'''<br />


==Overview==
==Structure of the Obg GTP-binding protein==
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.

== 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.
