OverProt: secondary structure consensus for protein families.

Summary: Every protein family has a set of characteristic secondary structures. However, due to individual variations, a single structure is not enough to represent the whole family. OverProt can create a secondary structure consensus, showing the general fold of the family as well as its variation.

2DProts: database of family-wide protein secondary structure diagrams.

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 2D diagrams.

CATH: increased structural coverage of functional space.

CATH (https://www.cathdb.info) identifies domains in protein structures from wwPDB and classifies these into evolutionary superfamilies, thereby providing structural and functional annotations.

Automated Family-Wide Annotation of Secondary Structure Elements.

Secondary structure elements (SSEs) are inherent parts of protein structures, and their arrangement is characteristic for each protein family. Therefore, annotation of SSEs can facilitate orientation in the vast number of homologous structures which is now available for many protein families. It also provides a way to identify and annotate the key regions, like active sites and channels, and subsequently answer the key research questions, such as understanding of molecular function and its variability.
