Validation of Time Series Technique for Prediction of Conformational States of Amino Acids

a project for fulfillment of M.Sc (Master of Science) in Bioinformatics.

Concepts

• Time series
• Protein's secondary structure
• Ramachandran Plot
• Feynman Problem Solving Algorithm

Description

• entries in PDBSelect (proteins) downloaded from PDB & curated.
• amino acid (AA) residue sequence used as Time Series by assigning Potential (normalized probability of occurrence of single amino acid residue in allowed conformational regions of Ramachandran plot).
• done :
  • development of novel clustering methods by evaluating various time series models (AR, ARMA, ARIMA)
  • forecasting of conformational states of AA & AA residues.
  • prediction of missing residues in proteins from PDB

Peoples
