  Selected figure(s)  
 
Figure 1.
Figure 1. Structure of E. coli YddE. (A) View of the dimer with the two separate domains from each subunit shown in blue and yellow. (B) Ribbon diagram of the molecule colored as in (A) and viewed perpendicular to the internal approximate 2-fold axis. The secondary structure elements are indicated. (C) Molecular surface representation of the molecule oriented 90° from (B). The large cleft at the domain interface is visible (center) with Cys72 indicated in red. (D) Close view of the predicted catalytic site with side-chains shown through a transparent surface and colored blue for domain 1 and yellow for domain 2. The glycerol molecule is shown in orange. (E) Ribbon diagram of DAP epimerase (accession number 1BWZ) oriented and colored as in (B). The regions that significantly differ from YddE are between DAP epimerase and YddE are indicated in orange.

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.
