The incorporation of glucose-% and 35S-labeled inorganic sulfate into heparin has been demonstrated in tissue slices of mouse mast cell tumors (1, 2). In addition, incorporation of 35S-labeled inorganic sulfate has been demonstrated in cell-free systems of DBA mouse mast cell tumors with 3’-phosphoadenosine 5’-phosphosulfate as a probable intermediate (3-6). However, the enzymatic reactions lea...

We examined the effects of oral glucosamine hydrochloride (GlcN), N-acetyl-D-glucosamine (GlcNAc) and d-glucose (Glc) administration on plasma total free amino acid (PFAA) concentrations in dogs. The PFAA concentrations increased in the control group and the GlcNAc group at one hour after feeding, and each amino acid concentration increased. On the other hand, in the GlcN group and the Glc grou...

Preceding experiments by Price and his associates establish that bovine pancreatic deoxyribonuclease is a glycoprotein which contains glucosamine and mannose. In order to determine the mode of attachment of the carbohydrate to the enzyme molecule, chromatographically purified deoxyribonuclease has been digested with Pronase. Gel filtration of the digest yielded a fraction containing all of the ...

BACKGROUND N-acetyl-β-D-glucosamine (GlcNAc) is widely used as a valuable pharmacological agent and a functional food additive. The traditional chemical process for GlcNAc production has some problems such as high production cost, low yield, and acidic pollution. Hence, to identify a novel chitinase that is suitable for bioconversion of chitin to GlcNAc is of great value. RESULTS A novel chit...
