    This study introduces a novel Applesoft BASIC program for predicting and graphing protein secondary structures. The tool utilizes Chou/Fasman rules, offering a user-friendly method for visualizing alpha-helix, beta-sheet, and coil structures.

    Area of Science:

    • Biochemistry and computational biology
    • Protein structure prediction
    • Bioinformatics software development

    Background:

    • Understanding protein secondary structure is crucial for predicting overall protein function.
    • Accurate prediction of secondary structures from amino acid sequences remains a challenge in bioinformatics.
    • Existing methods for secondary structure prediction can be computationally intensive or lack user-friendly visualization tools.

    Purpose of the Study:

    • To develop an accessible computational tool for visualizing protein secondary structures.
    • To implement the Chou/Fasman prediction rules within a user-friendly program.
    • To enable direct modification of predicted structures for refinement.

    Main Methods:

    • Development of an Applesoft BASIC program.

  • Application of Chou/Fasman rules for predicting alpha-helix, beta-sheet, and coil conformational parameters.
  • Graphical representation of predicted protein secondary structures.

    • Main Results:

    • The program successfully generates a graphical representation of protein secondary structure based on amino acid sequence.
    • It provides a first approximation of conformational parameters.
    • The inclusion of modification features allows for refinement of the plotted structure.

    Conclusions:

    • The developed program offers a straightforward method for predicting and visualizing protein secondary structures.
    • The graphical output is comparable to results obtained from X-ray crystallography and manual computations.
    • This tool can serve as a valuable aid in the initial analysis of protein conformational data.
