a The stereochemical analysis of Rab39a: The red area represents most favorable region of residues, yellow region is additionally allowed and light yellow region is generously allowed. The RC plot [19] represents 94.8% of residues in most favored region indicating a good quality model. b The local model quality of Rab39a: The protein score (− 5.88) falls in the range of PDB proteins submitted by NMR (dark blue region) and X-ray crystallography (light blue region), indicating a good quality model [19]. c ProSA energy plot of Rab39a: The graph shows local model quality by plotting energies as a function against amino acid sequence position. The ProSA [20] of the model shows maximum residues in the negative energy region. The negative ProSA energies of Rab39a indicate a reliable arrangement of residues in the 3D model
