The proteins having similar sequences may have similar structure” is the
philosophy of sequences prediction techniques. The 3D structures have structural and
functional importance for drug designing. Homology modeling, threading and ab initio
approaches are the computational techniques to predict the 3D structure of the proteins
for further studies. In this chapter, we will precisely elaborate numerous tools of 3D
structure prediction.
Keywords: ab initio, Homology modeling, I-Tasser, MODELLER, Structure
prediction, Threading.
