Using a combination of conventional and affinity chromatographic techniques, we have purified a uridine diphospho-N-acetylglucosamine:polypeptide beta-N-acetylglucosaminyltransferase (O-GlcNAc transferase) over 30,000-fold from rat liver cytosol. The transferase is soluble and very large, migrating with an apparent molecular weight of 340,000 on molecular sieve chromatography. Analysis of the purified enzyme on sodium dodecyl sulfate-polyacrylamide gel electrophoresis reveals two protein… CONTINUE READING
