Crystal structure of ScpB from Chlorobium tepidum, a protein involved in chromosome partitioning.
J.S.Kim, D.H.Shin, R.Pufan, C.Huang, H.Yokota, R.Kim, S.H.Kim.
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.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
