PubMed Abstract:
We determined the three-dimensional structure of a complex between an archaeal nicotianamine synthase homologue and a chemically synthesised reaction intermediate. This structure suggests that the enzymes cavity allows both an ordered substrate binding and provides energetic coupling of the reaction intermediate formation and translocation.
