The Helical Wheels Window has two viewing frames, each with two main
areas. Helices from the current structural model are displayed in pages
of 4 wheels each, using either frame.The two frames operate identically,
and allow up to eight helical wheels to be viewed simultaneously.
The helical spans in the current structural model are identified, and
represented as wheels, with each residue positioned 100 degrees around
from the previous, and represented by color coded circles. Coding is
according to the current index.
The picture shows the first eight helices from the model structure for
cytochrome b from the bc-complex of Rb. sphaeroides. The current
index is the Kyte-Doolittle hydropathy index. Hydrophobic residues are
yellow; polar, uncharged residues are green; acidic residues are red;
basic residues are blue.
- The main display, showing the wheels
- The Information area, showing:
- The position of the helix in the sequence
- The sequences, color coded according to the current index;
- The value and angle of the Moment Vector
The Helical Cylinders Window shows six helices from the structural model,
represented as helical cylinders. The helices are displayed in pages of
6 helices. Selection of helical spans, color coding, etc. are as for the
