PubMed Abstract:
Structural maintenance of chromosome (SMC) proteins are essential in chromosome condensation and interact with non-SMC proteins in eukaryotes and with segregation and condensation proteins (ScpA and ScpB) in prokaryotes. The highly conserved gene in Chlorobium tepidum gi 21646405 encodes ScpB (ScpB_ChTe). The high resolution crystal structure of ScpB_ChTe shows that the monomeric structure consists of two similarly shaped globular domains composed of three helices sided by beta-strands [a winged helix-turn-helix (HTH)], a motif observed in the C-terminal domain of Scc1, a functionally related eukaryotic ScpA homolog, as well as in many DNA binding proteins.
