The structures of the entire population of sialylated asparagine-linked oligosaccharides present on bovine fetuin were elucidated. Asparagine-linked oligosaccharides were released from fetuin with N-glycanase, radiolabeled by reduction with NaB[3H]4, and fractionated by anion-exchange high performance liquid chromatography (HPLC), ion-suppression amine(More)
gamma-Secretase is a membrane-associated endoprotease that catalyzes the final step in the processing of Alzheimer's beta-amyloid precursor protein (APP), resulting in the release of amyloid beta-peptide (Abeta). The molecular identity of gamma-secretase remains in question, although recent studies have implicated the presenilins, which are(More)
Recombinant human tissue plasminogen activator (rt-PA), produced by expression in Chinese hamster ovary cells, is a fibrin-specific plasminogen activator which has been approved for clinical use in the treatment of myocardial infarction. In this study, the structures of the Asn-linked oligosaccharides of Chinese hamster ovary-expressed rt-PA have been(More)
The Zap1 transcription factor of Saccharomyces cerevisiae and the Loz1 transcription factor of Schizosaccharomyces pombe both play a central role in zinc homeostasis by controlling the expression of genes necessary for zinc metabolism. Zap1 activates gene expression when cells are limited for zinc, while Loz1 is required for gene repression when zinc is in(More)
We have developed a highly efficient system for producing hepatitis B virus surface antigen in cultured mammalian cells. This system utilizes a recombinant bovine papilloma virus in which the hepatitis surface antigen coding sequences are inserted into the 5' untranslated region of the mouse metallothionein-I gene. Mouse fibroblasts stably transformed with(More)
Glycolysis and the pentose phosphate pathway both play a central role in the degradation of glucose in all domains of life. Another metabolic route that can facilitate glucose breakdown is the gluconate shunt. In this shunt glucose dehydrogenase and gluconate kinase catalyze the two-step conversion of glucose into the pentose phosphate pathway intermediate(More)
Hepatitis C virus infection (HCV) alarmingly increases worldwide; it causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma, so there is urgent need of developing effective and sufficient quantity of vaccine. HCV envelope protein E2 is the main target for developing as a vaccine candidate. Presently recombinant proteins can successfully be(More)
