Glycogen debranching enzyme (980-990)

Glycogen debranching enzyme (980-990) is a synthetic peptide fragment corresponding to amino acid residues 980 to 990 of the human glycogen debranching enzyme. As a peptide compound, it represents a defined segment of a key metabolic enzyme involved in glycogen catabolism, specifically participating in the breakdown of branched glycogen molecules within cells. This peptide region is of particular interest in biochemical research due to its potential involvement in the catalytic or regulatory domains of the full-length enzyme, making it a valuable tool for dissecting protein structure-function relationships and post-translational modifications relevant to glycogen metabolism.

Enzyme structure-function analysis: Researchers utilize this peptide fragment to investigate the structure-function relationship of the glycogen debranching enzyme. By focusing on the 980-990 amino acid region, scientists can examine how this specific sequence contributes to the overall enzymatic activity, substrate recognition, or conformational stability. Such studies are instrumental in mapping critical residues necessary for catalytic efficiency or interaction with other glycogenolytic proteins, thereby advancing the understanding of glycogen metabolism at a molecular level.

Epitope mapping and antibody production: The defined sequence of the 980-990 region serves as an ideal antigenic determinant for generating sequence-specific antibodies. These antibodies can be employed in immunodetection assays, such as Western blotting or immunoprecipitation, to selectively recognize the glycogen debranching enzyme or to study its expression and localization in various tissue samples. The peptide thus enables the development of precise immunological tools for probing metabolic regulation and protein-protein interactions in glycogenolytic pathways.

Protein-protein interaction studies: The peptide fragment is valuable for elucidating protein interaction networks involving the glycogen debranching enzyme. By serving as a bait in pull-down assays or as a competitor in binding studies, it allows researchers to identify and characterize interacting partners that associate with this specific region. Such analyses help clarify the molecular mechanisms underlying enzyme regulation, complex assembly, and the coordination of glycogen breakdown.

Post-translational modification research: The 980-990 segment may encompass or be proximal to sites of post-translational modifications such as phosphorylation or acetylation. Synthetic access to this peptide enables targeted studies on how such modifications affect enzyme function, localization, or stability. Researchers can use the peptide in vitro to assess modification patterns, develop site-specific antibodies, or perform mass spectrometry-based analyses, thereby providing insights into dynamic regulatory processes controlling glycogen metabolism.

Peptide-based assay development: The defined nature of the 980-990 peptide supports its use as a standard or control in biochemical assays involving the glycogen debranching enzyme. Its application in ELISA, competitive binding assays, or enzyme activity measurements facilitates method development and assay validation. By providing a consistent and well-characterized reagent, the peptide enhances the reproducibility and specificity of experimental workflows in metabolic research and enzyme characterization.
