Summary
Secondary structures provide a deep insight into the protein architecture. They can serve for comparison between individual protein family members. The most straightforward way how to deal with protein secondary structure is its visualization using 2 D diagrams. Several software tools for the generation of 2 D diagrams were developed. Unfortunately, they create 2 D diagrams based on only a single protein. Therefore, 2 D diagrams of two proteins from one family markedly differ. For this reason, we developed the 2DProts database, which contains secondary structure 2 D diagrams for all domains from the CATH and all proteins from PDB databases. These 2 D diagrams are generated based on a whole protein family, and they also consider information about the 3 D arrangement of secondary structure elements. Moreover, 2DProts database contains multiple 2 D diagrams, which provide an overview of a whole protein family's secondary structures. 2DProts is updated weekly and is integrated into CATH.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
