  ABSTRACT  
 

 
  Selected figure(s)  
 
Figure 1.
Figure 1. (A) Ribbon diagram of osmotin viewing along the cleft. The three domains are colored red (domain I), blue (domain II), and yellow (domain III). N- and C-termini are labeled. Residues (Glu84, Asp97, Asp102, and Asp185) around the acidic cleft are drawn in green stick models. The figure was drawn using MOLSCRIPT.[16] (B) Stereo diagram of the superposition of the C traces of osmotin (red), PR-5d (magenta), zeamatin (green), and thaumatin (blue) in the same orientation with (A). An arrow indicates the thaumatin loop in domain I.
Figure 2.
Figure 2. Surface representation of the clefts of osmotin (A), PR-5d (B), zeamatin (C), and thaumatin (D), depicting the electrostatic potential with a color scale that varies from blue to red, representing positive and negative potential, respectively.

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 code is shown on the right.
