Topology of beta-strands in "Greek-key" protein motif.

Protein topology refers to mutual orientation of regular secondary structures, such as alpha-helices and beta strands in protein structure [1] [1]. For example, two adjacent interacting alpha-helices or beta-strands can go in the same or in opposite directions. Topology diagrams of different proteins with known three-dimensional structure are provided by PDBsum (an example).
