The various levels of organization of protein structure given by Linderstὃrm-Lang are as follows: Primary structure of protein;Secondary structure of protein;Tertiary structure of protein;Quaternary structure of protein.
Graph Representation Learning for Protein Classification
Published in Ranjeet Kumar Rout, Saiyed Umer, Sabha Sheikh, Amrit Lal Sangal, Artificial Intelligence Technologies for Computational Biology, 2023
The tertiary structure of protein molecules occurs due to interaction between the side chains present in the amino acids. The common features of protein tertiary structure reveal much about the biological functions of the proteins and their evolutionary origins. If the tertiary structure of a protein is disrupted, it loses its activity.

The Protein Data Bank PDB (Berman et al. 2000) (http://www.rcsb.org/pdb/home/home.do) is the largest and most commonly used repository; from which information regarding proteins is utilised. The most popular techniques in obtaining protein tertiary structure include the X-ray crystallography and nuclear magnetic resonance (Robillard et al. 1976; Billeter 1992; Drenth 1999). From the PDB (Berman et al. 2000) database, three proteins viz. 2LEP, 3V2J and 3V2M in the standard .pdb format are collected and are shown in Figure 1. The tertiary structure is represented in a standard Cartesian coordinates of the atoms presented in the protein 2LEP is shown in Figure 2.
