Immunoglobulin family adhesion protein

This page uses the Jmol java applet. Be sure your browser is java-enabled. Be patient--it may take a while for the structure to load! After it loads, you can drag the structure to rotate it or shift-drag to zoom. If you have a 2-button or 3-button mouse, the right-button may give you more display options.

This is the structure of a domain of immunoglobulin family adhesion protein (Protein Data Bank structure 1GYA), determined by NMR spectroscopy. It contains a single N-linked high mannose carbohydrate chain, attached to Asn-65. In this case, the carbohydrate appears to be important in stabilizing the protein conformation, especially around Lys-61 (Wyss et al., Science 269:1273, 1995).

Color scheme:

• Green ribbon = protein backbone
• Red sticks = Asn-65
• Gray/white/red sticks = carbohydrate chain
• Blue sticks = Lys-61
