    Abstract: A chemoenzymatic method for the preparation of a core-fucoslyated glycoprotein or glycopeptide, including (a) providing an acceptor selected from the group consisting of a fucosylated GlcNAc-protein and fucosylated GlcNAc-peptide; and (b) reacting the acceptor with a donor substrate including an activated oligosaccharide moiety, in the presence of an endoglycosidase (ENGase) selected from Endo;F1, Endo-F2, Endo-F3, Endo-D and related glycosynthase mutants to transfer the oligosaccharide moiety to the acceptor and yield the structure defined core-fucosylated glycoprotein or glycopeptide. The donor substrate includes, in a specific implementation, a synthetic oligosaccharide oxazoline. A related method of fucosylated glycoprotein or fucosylated glycopeptide remodeling with a predetermined natural N-glycan or a tailor-made oligosaccharide moiety, and a method of remodeling an antibody to include a predetermined sugar chain to replace a heterogeneous sugar chain, are also described.

  • Patent number: 9528137
    Abstract: Cell-free protein synthesis systems and methods of using the same for producing in vitro protein materials in high yield are disclosed. The cell-free protein synthesis platform includes (a) a Saccharomyces cerevisiae cellular extract prepared from mid-exponential to late-exponential batch cultures in the range from about 6 OD600 to about 18 OD600 or fed-batch cultures harvested in mid-exponential to late-exponential phase; (b) a reaction buffer; and (c) a translation template or (c?) a transcription template from which a translation template can be prepared in situ with an RNA polymerase. A method of performing high-throughput protein synthesis in vitro is also provided that utilizes a combined transcription/translation reaction with the cell-free protein synthesis platform from Saccharomyces cerevisiae, an RNA polymerase and a transcription template prepared from a source DNA using an amplification procedure.

  • Patent number: 9464109
    Abstract: A method for the introduction of a labeling structure such as fluorescent molecules or a Raman tag to a compound is described. Imidazole functionalized resins or polymers are used to selectively immobilize phosphocompounds without protecting the carboxylic groups is described. Relying on the pKa difference between amines and hydrazides and carrying out the reaction in a slightly acidic buffer, all of the amines are protected by protonation while the hydrazides react with the phosphate imidazolide to form a phosphoramidate bond.
