Figure 1. Crystal structure of CyPA complexed with a
fragment of HIV-1 gag protein. (a) Molecular surface charge
distribution: the positively charged regions are shown in blue
and negatively charged regions are in red. The 25-mer of gag
capsid protein is represented in green and its sidechains are in
yellow. (Figure drawn using GRASP [49].) (b) Ribbon
representation: helices are shown in red, b strands in orange
and loops in blue. Residues of the 25-mer are shown as a yellow
stick model. (Figure plotted using the program MOLSCRIPT [50]
and Raster3D [51].)
