Figure 1.
Figure 1. Monomer and tetramer structures of H. pylori ENR and electron density maps of the bound ligands. (A) Monomer structure. Secondary structure elements were defined by PyMOL (DeLano, 2002, The PyMOL Molecular Graphics System, NAD^+ and triclosan bound to the active site of subunit A are shown as ball-and-stick models. (B) Tetrameric architecture. NAD^+ and triclosan are shown. (C) 2F[o]-F[c] electron density maps of the bound ligands, superimposed on triclosan (subunit A), diclosan (subunit A), and NAD^+ (subunit A of the triclosan complex). (D) Superposition of triclosan (cyan) and diclosan (purple). Phenolic rings (ring A) of triclosan and diclosan are superimposed.

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.
