Figure 8

Stereo images of the 1–3 and 1–4 subunit interfaces of BBP-A and AVD. (a) The 1–3 subunit interface of the AVD [PDB: 1VYO] [68] structure superimposed with the corresponding interface of the BBP-A – BSO structure. The carbon atoms of amino acids from BBP-A and AVD are coloured light grey and blue, respectively. Amino acids and β-sheets are numbered. Two occurrences of Ala97 in the BBP-A structure are indicated by arrows. (b, c) A simplified view of the 1–4 interface of the BBP-A – BSO (b) and AVD [PDB: 2AVI] [9] (c) structure after superimposition. The atoms of the non-conserved side chains of amino acids within 4 Å of subunit 1 of either the BBP-A or AVD structure are shown. For clarity, Met96 and Thr110 of BBP-A as well as the equivalent residues of AVD (Thr95 and Asp109) are not shown, and only one half of the symmetrical 1–4 interface is shown. The carbon atoms of residues from subunit 1 and 4 are respectively coloured light grey and green in BBP-A, and grey and blue in AVD. Amino acids and β-sheets are numbered.
