Fig. 4From: Combining functional metagenomics and glycoanalytics to identify enzymes that facilitate structural characterization of sulfated N-glycansIn vitro expression of sulfatase candidates. A SDS-PAGE of 8 sulfatases produced with the PURExpress® system. Expressed enzymes are shown with a red triangle. B Activity of in vitro expressed sulfatases. Sulfatases were assayed on 4MU-GlcNAc-6-SO4 in the presence and absence of exogenous hexosaminidaseBack to article page
