Topology of protein metastructure and $\beta$-sheet topology
Topology of protein metastructure and $\beta$-sheet topology
We introduce a new, simplified model of proteins, which we call protein metastructure. The metastructure of a protein carries information about its secondary structure and $\beta$-strand conformations. Furthermore, protein metastructure allows us to associate an object called a fatgraph to a protein, and a fatgraph in turn gives rise to …
