Figure 6 Ligand binding in TRY-LYS2. (a) `Omit' maps calculated
as for Fig. 4-(a), at the same contour levels and with similar
colouring scheme. Sites 2004-2006 are not occupied in this
structure, as shown by the absence of difference density. There
is an indication of a double conformation of the Lys side chain,
not modelled because of weak density level for refinement. The
water at 2102 has been modelled in two alternative
conformations: 2102b is at a bonding distance to Lys N ,
whilst 2102a is at clashing distance, binding in the absence of
the peptide ligand. (b) Geometry of the binding site. The
labelling scheme is similar to Fig. 4-(b). Some atoms have been
omitted for clarity.
