Figure 9From: The two tryptophans of β2-microglobulin have distinct roles in function and folding and might represent two independent responses to evolutionary pressureComparison between β2-m cavity accommodation of residue 95 in Trp95Leu mutant (A) and wild-type (PDB code 1LDS) (B). Residues Ser11, Asn21, Pro72 and Tyr78 are shown in red as sticks and space-fill dots. Residue 95 is shown in cyan.Back to article page
