FAMS and FAMSBASE for protein structure

Area of Science:

• Computational biology
• Structural bioinformatics
• Protein modeling

Background:

• Homology modeling is crucial for predicting protein structures when experimental data is unavailable.
• Accurate protein structure prediction aids in understanding protein function and designing drugs.
• Existing homology modeling methods often require significant user expertise and manual intervention.

Purpose of the Study:

• To introduce the Full Automatic Modeling System (FAMS), a novel computational tool for protein homology modeling.
• To demonstrate the automated nature of FAMS, reducing the need for specialized user knowledge.
• To achieve accurate protein structure models through an efficient and automated workflow.

Main Methods:

• FAMS employs an algorithm integrating database searches with simulated annealing.
• The system automates the entire homology modeling process, from template identification to final model refinement.
• Torsion angles of protein backbones and sidechains are optimized for accuracy.

Main Results:

• FAMS successfully generates protein models with highly accurate backbone and sidechain torsion angles.
• The automated operations of FAMS eliminate the need for specialized user knowledge or experience.
• Biologically relevant protein structures can be obtained efficiently using this system.
