PEPstrMOD
:: DESCRIPTION
The PEPstrMOD server predicts the tertiary structure of small peptides with sequence length varying between 7 to 25 residues. It also handles peptides having various modifications like non-natural residues, terminal modifications (Acetylation/Amidation), Cyclization (N-C, disulfide bridges), conversion of L- to D- amino acids, post translational modifications, etc. The prediction strategy is based on the realization that β-turn is an important and consistent feature of small peptides in addition to regular structures. Thus, the method uses both the regular secondary structure information predicted from PSIPRED and β-turns information predicted from BetaTurns. The structure is further refined with energy minimization and molecular dynamic simulations.
