Below shows 3D Images of many proteins (copied from http://www.rcsb.org) along-side their corresponding Distance and Contact Maps (made at http://nanohub.org/resources/contactmaps using each protein's *.pdb file). Most proteins were chosen to represent different classes within the SCOPe database (http://scop.berkeley.edu). SCOPe classes a to j are natural proteins and peptides. Ones in class k are designed proteins.

Each 3D Image below uses a color scheme in which low-numbered residues are blue while high-numbered residues are red. Some images come from NMR ensembles and so show multiple strands of the same protein with the same coloring but slightly different conformations.

Each Distance Map below shows the Cα-Cα distance between every pair of amino acids in the protein as a two-dimensional matrix of shaded pixels. Dark pixels represent close pairs of residues. Light pixels represent distant pairs of residues. Low-numbered residues are in the lower left. High-numbered residues are in the upper right. Images labeled "Distance Map 1" show the 1st conformation from an NMR ensemble in which the same protein exists in multiple slightly-different conformations.

Each Contact Map below shows the Cα-Cα distance between every pair of amino acids in the protein as a two-dimensional matrix of shaded pixels. Black pixels represent pairs of residues less than 8 Angstroms apart. White pixels represent pairs of residues at least 8 Angstroms apart. Low-numbered residues are in the lower left. High-numbered residues are in the upper right. Images labeled "Contact Map 1" show the 1st conformation from an NMR ensemble in which the same protein exists in multiple slightly-different conformations.

If all the images below were scrambled, could you use your pattern-recognition skills to pick which ones went together? See http://memorize.com/distance-and-contact-maps to find out!
