A study was carried out to predict the 3D structure and function of an unidentified wheat protein (CAA35597.1) using LOMETS and I-TASSER servers. The servers were able to predict a high quality 3D structure of the wheat protein based on its amino acid sequence. The predicted structure was further analyzed and accepted in the Protein Model Database.

2. In-silico analysis of proteins
A study was carried out to investigate the in-silico analysis of 2D and
3D structure prediction of protein with an unidentified structure and
function in Triticum aestivum.
Primary structure prediction and physicochemical were
characterization(PROTPARAM)
A high quality 3D structure and function of Wheat protein
(CAA35597.1) from NCBI has been predicted for the hypothetical amino
acid sequence using LOMETS (LOcal MEta-Threading-Server) and ITASSER (Iterative Threading Assembly Refinement) servers Page 2

7. Future Aspects
•The predicted structure can further be validated by wet lab
experiments.
•Using the predicted cleavage site we can construct the resistant
variety
•The PDB file can be submitted to Protein Databases for homology
search
•Compare structures
Homologous
Mutants
With or without ligands
