Figure 2 The Alba dimer. (A) Stereo views of the dimer coloured
by B-factor (dark blue to deep red representing a span of
B-factor from 30 to 100 Å^2). The lower view is related to
the upper view by a 90° rotation around a vertical axis. The
strands and helices of one monomer are labelled as in Figure 1.
The N- and C-termini are highlighted by blue and red spheres,
respectively. Lysines 16 and 17 are also shown. (B) Orthogonal
views of the dimer showing the location of exposed residues
conserved across the Archaea: A (Gly15, Lys17, Pro18, Asn21,
Tyr22), B (Lys40, Arg42, Glu91) and C (Phe60). (C) Stereo view
of the Alba dimer coloured by electrostatic potential. The
groove formed between the two loops containing Lys16 and Lys17
is apparent. Figures 2, 3 and 5 were drawn with BOBSCRIPT
(Esnouf, 1997) and GL_RENDER (L.Esser and J.Deisenhofer,
unpublished).
