Does ImpaRATOR cleave at all O-glycosylated sites?
ImpaRATOR has a broad activity towards different O-glycan structures; however, the enzyme has limited activity towards sites with two adjacent O-glycosylated Ser/Thr residues. For complete information about O-glycan sites in glycoprotein substrates containing several sites with two adjacent O-glycosylated Ser/Thr residues, OpeRATOR may be a better option.
