Anchored clathrate water comparison. Waters located down the TQTA trough of Pb INP (middle image) show near identical coordination as compared to the ice-like waters located down the TxT troughs of Tm AFP (PDB 1EZG (chain A)) (right image) and sbwAFP (PDB 1M8N (chain A)) (left image) as revealed by X-ray crystallography. Hydrogen bonds are represented by black hatched lines, while oxygens are coloured red, and nitrogens dark blue. Waters are represented as red spheres.
