This shows a "cartoon" representation of a single immunoglobulin domain. This is actually the constant domain from a light chain (residues 105-214). Notice the 4+3 = 7 antiparallel beta strands forming two beta sheets, which are pinned together by a disulfide bond (yellow rod). This shows RasMol's "group" color scheme, in which a polypeptide is colored in a rainbow sequence from end to end.
