  Selected figure(s)  
Figure 1.
Figure 1. (a) Structure of the CPSF5 dimer (SO[4]-bound form). Nudix fold and additional secondary structure elements are colored respectively in cyan and blue for one monomer and purple and red for the other. Atoms of the sulfate ions are shown as spheres. The flexible Phe103 side chain is shown as a stick model with carbons colored in orange. The N-terminal peptides forming crystal interactions with the 2- 9 surfaces are also shown as a C trace, the C and the nitrogen of their N-terminal residue being shown as spheres (residues 21-32 of the apo form in green, and residues 22-32 of the SO[4]-bound form in yellow). (b) Sequence of the constructs 1 and 2. The sequence of human CPSF5 is depicted, the sequence of constructs 1 and 2 being boxed in red and green respectively.
Figure 3.
Figure 3. Molecular surface representation around the sulfate-binding site including residues potentially involved in catalysis or recognition. Glu170 provides second sphere stabilization of Arg150. Negatively and positively charged potentials are colored in red and blue, respectively. Tube representation of the C -trace of CPSF5 is colored in green. Conserved polar residues in the channel are represented as stick models. Atoms of the sulfate ion are shown as balls.

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.
