H-site features. a) Stereo representation of the H-site of Na-GST-2, residues that form the cleft are shown as sticks. b) The C-terminal loop of Na-GST-2 is stabilized by a network of hydrogen bonds, residues involved in these interactions are shown in as sticks, while the bonds are indicated by dashed lines and distances are shown. Residues are colored in rainbow representation from N-terminal to C-terminal (Blue-Green-Yellow-Orange-Red). Two ethylene glycol molecules (EDO, in cyan) from the cryo-protecting liquor are visible in the surface of the H-site.
