Secondary Structure Graphs & Chain Graphs#
In this tutorial, we’ll be looking at higher-order graphs - that is graphs of Secondary Structure Elements and interacting chains (quaternary structure) - as well as assorted visualisation tools.
Graphein provides utilities for computing these graphs from residue-level graphs. I’d recommend checking out `this tutorial <>`__ for more information.
First, we’ll construct a graph to work with
[1]:
# Install Graphein if necessary
# !pip install graphein
# Install DSSP if necessary
# !sudo apt-get install dssp (better for colab) OR !conda install -c salilab dssp

Secondary Structure Graphs#
We use [DSSP] to compute secondary structures. This is stored under d["ss"] in the node attributes. Eg:
[3]:
g = gp.secondary_structure(g)
for n, d in g.nodes(data=True):
print(d["ss"])
if d["ss"] == "T":
break

We can compute either a multigraph, where each edge in the selection is preserved (e.g. multiple edges between nodes H1 and H2 are permitted), or a weighted graph where we aggregate multiple edges between a pair of nodes into and preserve the edge information as metadata.
MultiGraph#
[4]:
ss_graph = gp.compute_secondary_structure_graph(g, remove_self_loops=True)
print(nx.info(ss_graph))
for u, v, d in g.edges(data=True):
print(u, v, d)
Name: 4hhb
Type: MultiGraph
Number of nodes: 80
Number of edges: 107
Average degree: 2.6750

Chain Graph#
Chain graphs represent the quaternary structure of a protein complex; nodes represent individual chains and edges are the interactions between them. Again, we can compute either a multigraph or a weighted graphs.
