Location of high Fit value sites for ubiquitin. Six of the seven highest Fit value sights in ubiquitin are shown in cyan in this MacPyMOL model of 1AAR. The site with the highest Fit value in the entire protein was Gly-47, immediately next to the Lys-48 binding site, a possible indication that it plays a key role in permitting Lys-48 to undergo binding. The other 5 sites appear to perform a critical role in the conformation of the binding domain.
