The molecular packing and unit cells of L-Phe:D-Abu (space group P212121), L-Phe:D-Nva (P212121) and L-Phe:D-Met (P21), together with L-Val:D-Met (P212121; Dalhus & Görbitz, 1999c), L-Ile:D-Nva (C2; Dalhus & Görbitz, 1999a) and D-Nle:L-Met (P21; Dalhus & Görbitz, 1999b), with Cambridge Structural Database refcodes (Allen, 2002). A hydrophobic interface has been indicated for L-Phe:D-Abu; circles highlight different Met conformations. (In the electronic version of the paper, colouring of side chains has been used to emphasize structural similarities and not the chirality of the amino acid.) |
