Purified beta1,2-xylosyltransferase and uses thereof

摘要

The present invention provides a purified, homogeneous plant enzyme that adds a beta-1,2-linked xylose to the beta-linked mannose on the N-linked oligosaccharides of storage glycoproteins. This beta1,2-xylosyltransferase was purified from the microsomal fraction of soybean cells approximately 51,000-fold. Also provided is polyclonal antiserum recognizing this delta1,2-xylosyltransferase enzyme and uses thereof.
