Common NameCadystin A
DescriptionCadystin A is a gamma-glutamyl peptide belonging to the class of metal-binding peptides. It has been characterized through advanced analytical techniques, including positive fast atom bombardment tandem mass spectrometry (FAB-MS/MS), which has been instrumental in elucidating its structure and determining the gamma glutamyl linkage that is crucial for its function. Specifically, Cadystin A is identified as Cadystin (gamma EC)3G, with a molecular weight of 771, while its related compound, Cadystin B, is noted as Cadystin (gamma EC)2G, with a molecular weight of 539 (PMID:1368589 ). The unique gamma-glutamyl structure of Cadystin A suggests potential biological roles in metal ion binding, which may be relevant in various physiological and biochemical processes. Further investigation into its biological activities could provide insights into its functionality and potential applications in biomedical research.
