The crystallization procedure used to obtain the 9PAP structure was carried out using a 62% (w/w) methanol and water crystallization medium.  Thus, the papain in this crystal structure is coordinated by <scene name='Sandbox_30/Papain_methanol/1'>methanol molecules</scene>, 29 of which are shown, and <scene name='Sandbox_30/Papain_water/1'>water molecules</scene>, 21 of which occur between adjacent papain molecules and probably important in maintaining their structural integrity<ref name="9PAP PDB" />.  Both

<scene name='Sandbox_30/Papain_methanol_h-bondint/1'>methanol</scene> (red and grey) and <scene name='Sandbox_30/Papain_water_h-bonds/3'>water</scene> (purple) molecules form a hydrogen bonds with many different residues, which are shown as ball and stick structures in the diagrams. Some of the ethanol molecules also have <scene name='Sandbox_30/Papain_methanol_hydrophobicint/3'>hydrophobic interactions</scene> with the enzyme.
