    Area of Science:

    • Biochemistry and Molecular Biology
    • Protein Chemistry
    • Physiological Regulation

    Background:

    • Proteolytic processing is a fundamental mechanism for physiological regulation.
    • It involves post-translational cleavage of specific peptide bonds in protein precursors.
    • This cleavage induces conformational changes, activating or modifying protein function.

    Purpose of the Study:

    • To extend the understanding of proteolytic processing beyond model zymogens.
    • To investigate complex physiological regulation systems involving proteolytic events.
    • To explore the contribution of proteolytic processing to protein structure, domain organization, and evolution.

    Main Methods:

    • Utilized protein chemistry techniques.
    • Employed molecular biology methodologies.
