Title:

Crystal structure of ScpB from Chlorobium tepidum, a protein involved in chromosome partitioning.

Journal:

Proteins. 2006 Feb 1;62(2):322-8.

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.
