Structural overview of nAGE10. (a) The contents of the asymmetric unit of the nAGE10 structure, with the nAGE10 monomer shown from the side in a cartoon representation. It is coloured using a green–blue palette from the N-terminal to the C-terminal residues. Waters are shown as red, nonbonded spheres. Ethylene glycol molecules (three) are represented as yellow sticks and the buried chloride ion as a green sphere. (b) The nAGE10 monomer, shown from the front (the face where the α-helices that form the barrel are linked by short loops). Each helix is numbered (H1–H12) according to its placement in the amino-acid sequence. (c) The nAGE10 dimer. Generation of symmetry mates within 3 Å of nAGE10 reveals the presence of an additional monomer for which dimer association is probable involving the fronts of the monomers. Red arrows indicate the extremities of the disordered loop (residues 156–165). |
