Figure 3
A selection of model-viewing options in ArpNavigator depicted for PDB structure 3l9a : the C-terminal domain of a Streptococcus mutans hypothetical protein (Midwest Center for Structural Genomics, unpublished work). Shown clockwise from the top left are a stick representation in solid electron density (50% opacity, 1.5[sigma]), a ball-and-stick representation in planar density, also showing a `scaleometer' and the contour levels of shown electron densities, a skeleton representation of the electron density shown as a mesh and the protein in cartoon representation in planar density.  [article HTML]
