Figure 1.
Figure 1. Crystal structure of 13879369 from Mouse. (A) Ribbon diagram color-coded from N-terminus (blue) to C-terminus (red) showing the domain organization. Helices H1-H4 and -strands 1- 7 are indicated. The partial disulfide bond between Cys35 and Cys62 is shown in ball-and-stick. (B) Diagram showing the secondary structure elements in 13879369 superimposed on its primary sequence. The -helices, -strands, -bulges, -turns and disordered regions (dots) are indicated. The -sheet strands are indicated by a red A and B. -Hairpins are depicted as red loops.
Figure 2.
Figure 2. (A) Protein 13879369 in surface representation showing the putative active site cavity with neighboring residues in sticks. Two formic acid and three water molecules located inside the cavity are depicted in sticks and red balls, respectively. (B) Superposition of 13879369 (blue and red) and Ytfp (gray) in ribbon representation. Regions where backbones deviate by RMSD > 4 Å are colored red in 13879369. The two formates shown in red and yellow spheres indicate the position of the putative active site cavity.

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.
