a Large overlap and (b) small overlap. The overlap values are, respectively, 9.8 × 10−2 and 4.7 × 10−2 Å3. The residues close to the terminal rings of Lut are shown for each case; residue names are given in the one-letter code. The arrows show the movement of the stromal loop with respect to the L1 pocket.
