Crystal structure of DCoH, a bifunctional, protein-binding transcriptional coactivator.

  ABSTRACT  
 
DCoH, the dimerization cofactor of hepatocyte nuclear factor-1, stimulates gene expression by associating with specific DNA binding proteins and also catalyzes the dehydration of the biopterin cofactor of phenylalanine hydroxylase. The x-ray crystal structure determined at 3 angstrom resolution reveals that DCoH forms a tetramer containing two saddle-shaped grooves that comprise likely macromolecule binding sites. Two equivalent enzyme active sites flank each saddle, suggesting that there is a spatial connection between the catalytic and binding activities. Structural similarities between the DCoH fold and nucleic acid-binding proteins argue that the saddle motif has evolved to bind diverse ligands or that DCoH unexpectedly may bind nucleic acids.

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.
