Glycopeptidase A is widely used in biochemical research for the selective cleavage of glycoproteins. It helps in the study of protein glycosylation by removing specific carbohydrate moieties, allowing researchers to analyze the structure and function of glycoproteins. This enzyme is particularly valuable in proteomics and glycobiology, where it aids in mapping glycosylation sites and understanding the role of glycans in cellular processes. Additionally, it is employed in the preparation of deglycosylated proteins for immunological studies, as it can enhance antigen detection by exposing hidden epitopes. Its specificity and efficiency make it a crucial tool in advancing research on glycoprotein-related diseases and therapeutic development.
