The GALNT7 protein serves as an indispensable glycopeptidyl transferase for O-linked oligosaccharide biosynthesis. Its enzymatic activity involves catalyzing the transfer of N-acetyl-D-galactosamine residues to pre-existing glycosylated peptides. GALNT7 Protein, Human (HEK293, His) is the recombinant human-derived GALNT7 protein, expressed by HEK293 , with C-6*His labeled tag.
