In the field of computational structural proteomics, contact predictions have
shown new prospects of solving the longstanding problem of ab initio protein
structure prediction. In the last few years, application of deep learning
algorithms and availability of large protein sequence databases, combined with
improvement in methods that derive contacts from multiple sequence alignments,
have shown a huge increase in the precision of contact prediction. In addition,
these predicted contacts have also been used to build three-dimensional models
from scratch.In this chapter, we briefly discuss many elements of protein
residue-residue contacts and the methods available for prediction, focusing on a
state-of-the-art contact prediction tool, DNcon. Illustrating with a case study,
we describe how DNcon can be used to make ab initio contact predictions for a
given protein sequence and discuss how the predicted contacts may be analyzed and
evaluated.
