Fructose-bisphosphate aldolase A isoform 2 (326-338)

Fructose-bisphosphate aldolase A isoform 2 (326-338) is a synthetic peptide fragment derived from the human aldolase A enzyme, specifically encompassing amino acid residues 326 to 338 of the isoform 2 sequence. As a segment of a key glycolytic enzyme, this peptide represents a functionally significant region involved in carbohydrate metabolism. Its defined sequence and origin make it a valuable molecular tool for research into enzyme structure, protein-protein interactions, and post-translational modification studies. The unique characteristics of this peptide fragment enable its use in a variety of biochemical and molecular biology applications, particularly those focused on elucidating the functional domains of aldolase A and their regulatory mechanisms.

Epitope mapping: Researchers frequently utilize this peptide as a defined epitope for mapping antibody binding sites or generating sequence-specific antibodies against aldolase A. By incorporating the 326-338 region into immunoassays or antibody production protocols, investigators can dissect the immunogenic landscape of the enzyme, identify conformational or linear epitopes, and validate antibody specificity. Such studies are instrumental in advancing the understanding of immune recognition of glycolytic enzymes and developing reliable immunodetection reagents for laboratory use.

Protein-protein interaction analysis: The peptide serves as a targeted probe for investigating the molecular interactions of aldolase A, particularly within the context of its C-terminal domain. Through techniques such as peptide pull-down assays, surface plasmon resonance, or co-immunoprecipitation, scientists can explore how this region mediates binding with regulatory proteins, cytoskeletal elements, or metabolic partners. These insights contribute to a deeper comprehension of the dynamic regulatory networks governing cellular metabolism and cytoskeletal organization.

Phosphorylation and post-translational modification studies: The defined sequence of the 326-338 fragment allows for detailed analysis of potential phosphorylation sites or other post-translational modifications. By exposing the peptide to kinases or modifying enzymes in vitro, researchers can identify modification patterns, assess enzyme specificity, and characterize the functional consequences of such modifications. These experiments are vital for unraveling the regulatory mechanisms that modulate aldolase A activity and its cellular localization in response to metabolic cues.

Structural and conformational studies: Synthetic peptides corresponding to specific regions of enzymes like aldolase A are commonly employed in structural biology to investigate local folding, secondary structure propensity, or peptide-ligand interactions. This particular fragment can be analyzed using techniques such as circular dichroism spectroscopy, nuclear magnetic resonance, or computational modeling to elucidate its conformational preferences. These findings enhance the understanding of structure-function relationships within the enzyme and support the rational design of peptide-based probes or inhibitors.

Peptide-based assay development: The 326-338 sequence can be integrated into custom assay platforms for studying enzyme kinetics, substrate recognition, or inhibitor screening. By providing a standardized peptide substrate or binding target, it enables the development of reproducible, high-throughput assays for biochemical research or compound discovery. Such applications streamline the investigation of aldolase A function and facilitate the identification of modulators with potential research or industrial relevance.
