This review comprises theoretical approaches and recent developments to describe the super-secondary and quaternary structure topology of a protein in a mathematically unique way. Based on the advances in experimental exploration of proteins and protein complexes, new extended abstract descriptions that include, for example, ligand information have been developed. A special focus concerns protein complexes and their description at secondary structure level as well as at quaternary structure level. Here, we give and discuss their unique graph-theoretic description and visualization. We highlight recent developments for applications to protein structure assembly.
