Figure 4

Backbone ribbon diagrams of hPRL-1-14-G129R (PDB: 2Q98) (left) and hGH (PDB: 1HGU) (right) with key side chains highlighted. Histidine side chains in the hPRL structure (H27, H30, H46, H59, H97, H138, H173, H180, and H195) and the homologous residues in hGH (H18, H21, P37, F54, F92, E129, Y164, D171, and E186) are shown in blue. Side chains involved in a hydrophobic cluster in hPRL (W91, P94, W150, L153, and L171) and their homologous counterparts in hGH (W86, P89, Y143, F146, and L162) are highlighted in red.
