Area of Science:

• Molecular systems biology
• Proteomics
• Interactomics

Background:

• Post-genomic research requires methods to manage large datasets from transcriptomics, proteomics, and metabolomics.
• Functional proteomics and interactomics are key to understanding biochemistry, drug discovery, and bioinformatics.
• Generating sub-proteomes is essential for reducing data complexity in proteomic studies.

Purpose of the Study:

• To develop molecular tools for generating activity- and affinity-based sub-proteomes.
• To utilize immobilized protein ligands for targeted protein capture.
• To investigate the use of modified hydroxamate inhibitors for metalloprotease sub-proteome generation.

Main Methods:

• Application of tailor-made molecular tools, specifically protein ligands.
• Utilizing immobilized protein ligands on solid supports like magnetic beads for affinity-based capture.
• Employing modified hydroxamate inhibitors targeting metalloproteases for sub-proteome generation.
• Surface Plasmon Resonance (SPR) for optimizing binding and elution conditions.

Main Results:

• Immobilized protein ligands are effective for sub-proteome generation via affinity chromatography and magnetic bead fishing.
• Hydroxamate-based inhibitors, like marimastat, can target active metalloproteases mechanistically.
• Modified hydroxamate inhibitors attached to magnetic beads show potential for activity- and affinity-based sub-proteome isolation.
• Preliminary results demonstrate the application of these probes in magnetic bead fishing experiments.

Conclusions:

• Tailor-made molecular tools, particularly immobilized ligands, are valuable for generating specific sub-proteomes.
• Modified hydroxamate inhibitors offer a mechanistic approach to isolate active metalloproteases.
• This strategy facilitates the study of functional proteomics and interactomics, advancing fields like medicinal chemistry and biotechnology.
