Figure 9
Scheme showing Hyp-1 saturation with ligand molecules in the crystal structure of 9Hyp/ANS. The 36 protein chains are grouped into two Rows, shown in pink (Row I; AB, …, QR) and green (Row II; ST, …, ij). The internal binding sites 1–3 are highlighted in yellow. Full ligand occupancy is marked by x or 2x to indicate the number of ligand molecules (one or two) found in the general area of the binding site. Partial occupancy is marked by the fractional value. For interstitial sites 4–8, the link to an adjacent protein molecule (and possible partial occupancy) is also indicated. The prime symbol (′) indicates symmetry-related molecules with respective binding sites. Ligand molecules differing from ANS (DMS, FLC, EPE and SO4) are denoted using their abbreviations and occupancies. |
