| 1.1.1.335 | in presence of NAD(H) and substrate to 2.13 A and 1.5 A resolution. Enzyme displays octameric quaternary structure with the active sites positioned far apart. The octamers can be envisioned as tetramers of dimers. The carboxylate group attached to the C-5' carbon of the hexose in the natural substrate, UDP-N-acetyl-D-glucosaminuronic acid, is held firmly in place in the enzyme WlbA active site by the side chains of Arg165 and Tyr169 | Bordetella pertussis |
