• PubMed Abstract: 
  

  Crystal structures are reported for free and coenzyme A (CoA) bound forms of the YfdW protein from Escherichia coli, a representative type III CoA transferase. The structures reveal a two-domain protomer with interdomain connections forming a ring-like structure with a large central hole. Two protomers associate to form a highly intertwined dimer in which the hole of each ring is filled by the partner molecule. Each protomer binds a single CoA molecule and these CoA-binding sites are distant from one another in the dimer.
