摘要： A one-pot glycosylation reaction is disclosed in which a mannosyl (Man) group is enzymatically transferred to an acceptor molecule. The starting glycoside is a mannosyl 1-phosphate that is enzymatically converted to its GDP derivative via UTP and a pyrophorylase. The formed GDP derivative is used in the enzyme-catalyzed glycosyl transfer. That enzyme-catalyzed glycosyl transfer to an acceptor releases GDP that is enzymatically converted to GTP for further conversion of mannosyl 1-phosphate into its GDP derivative. Also disclosed are a recombinant α1,2-mannosyltransferase that is enzymatically active, is dispersible in an aqueous reaction medium, and free of the transmembrane portion of the native enzyme, as well as DNA encoding that transferase, an expression vector containing exogenous DNA that encodes that enzyme and E. coli cells containing that vector.

摘要： Combinatorial libraries of HIV and FIV protease inhibitors are characterized by α-keto amide or hydroxyethylamine core structures flanked by on one side by substituted pyrrolidines, piperidines, or azasugars and on the other side by phenylalanine, tyrosine, or substituted tyrosines. The libraries are synthesized via a one step coupling reaction. Highly efficacious drug candidates are identified by screening the libraries for binding and inhibitory activity against both HIV and FIV protease. Drug candidates displaying clinically useful activity against both HIV and FIV protease are identified as being potentially resistive against a loss of inhibitory activity due to development of resistant strains of HIV.

摘要： Enzymatic sulfations of biomolecules catalyzed by 3′-phosphoadenosine-5′-phosphosulfate (PAPS) dependent sulfotransferases are enhanced by coupling the sulfation reaction an enzymatic regeneration of PAPS. The PAPS is enzymatically regenerated from its hydrolysis product 3′,5′-diphosphate (PAP) using recombinant aryl sulfotransferase as the catalyst and aryl sulfate as the substrate. Biomolecules capable of enhanced sulfation by this method include carbohydrates, oligosaccharides, peptides, proteins, flavonoids, and steroids. When enzymatic sulfation and substrate regeneration steps are coupled, the desulfated aryl group produced in the regeneration step has a spectroscopic signature that can be employed for monitoring the progress of the sulfation of the biomolecule.

摘要： Regioselective acetylation of the 9-hydroxyl group on N-acetylneuraminic acid is achieved enzymatically for producing oligosaccharides which contain a terminal N-acetylneuraminic acid moiety. This method provides access to O-acylated disialogangliosides as well as other N-acetyl-neuraminic acid oligosaccharides. These compounds are biologically and medicinally important and are difficult to obtain from nature or by chemical acylations. The methodology affords simple reaction conditions and minimal purification steps. In addition, the process affords good yields and the enzymes and reagents employed are commercially available with high stability and low costs.
