HIV-1 gp120 envelope glycoprotein complexed with CD4 antigen
Note: this page requires Java; if you do not have Java installed or it is not enabled, the molecular model will not be displayed in the lower left panel; you may try the non-Java version of the page here (it is slower).
Now let's look at the structure of the gp120 of HIV. In this image theare shown in dark pink and the in yellow-orange. The connecting segments are in white. The glycoprotein shown in the image below is not complete since the N-terminus is missing up to residue 89 . The protein chain is folded into an inner and an outer domain which are linked by an anti-parallel four-stranded bridging . This microdomain is also in contact with the and the . To see this rotate the molecule using the mouse or here . Also found extending from the outer domain is a region consisting of the beta 15 sheet and the . This is also in contact with the CD4 molecule.
