For H2O , we predict a binding site in the distal pocket ( DP ) , in agreement with crystallographic observations , and another one close to Leu 29 which explains the importance of this residue in controlling the pocket ' s hydrophobicity , as well as disordered minima in the largely apolar xenon cavities .
