Vestronidase alfa-vjbk (Mepsevii)

Recombinant human lysosomal beta glucuronidase (GUS) is intended to provide exogenous GUS enzyme for uptake into cellular lysosome; mannose-6-phosphate (M6P) residues on the oligosaccharide chains allow binding of the enzyme to cell surface receptors, leading to cellular uptake of the enzyme, targeting to lysosomes and subsequent catabolism of accumulated GAGs in affected tissues.
