Visualization of the second ProGolem rule instantiated with protein 1HIZ (covered by the rule). The hexose is the glucose molecule to the left, with a pink backbone. To the right, with a white backbone, are the amino acids ASN and GLU, in closer contact with the hexose. The dotted black lines highlight the distances between the atoms in the amino acids and the center of the hexose.
