摘要:
The present invention relates to a method for producing cytidine 5′-monophospho-N-acetyl-neuraminic acid (CMP-Neu5Ac, 1) from low-cost substrates N-acetyl-D-glucosamine (GlcNAc), pyruvate, cytidine and polyphosphate in a single reaction mixture with a set of optionally immobilized or optionally co-immobilized enzymes comprising N-acylglucoamine 2-epimerase (AGE), an N-acetylneuraminate lyase (NAL), an N-acylneuraminate cytidylyltransferase (CSS), a uridine kinase (UDK), a uridine monophosphate kinase and a polyphosphate kinase 3 (PPK3). Further, said process may be adapted to produce Neu5Acylated i.e. sialylated biomolecules and biomolecules including a saccharide, a peptide, a protein, a glycopeptide, a glycoprotein, a glycolipid, a glycan, an antibody, and a glycoconjugate, in particular, an antibody drug conjugate, and a carbohydrate conjugate vaccine, or a flavonoid.
摘要:
The disclosed subject matter provides methods using and kits comprising a compound of formula (I) or a hydrate, a solvate, or a pharmaceutically acceptable salt thereof. The disclosed subject matter further provides a method of treating one or more symptoms of cancer comprising administering to a subject in need thereof a compound of formula (I) and a process for preparing such.
摘要:
The invention provides isolated nucleic acids molecules, designated 57658 nucleic acid molecules, which encode novel uridine kinase family members. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing 57658 nucleic acid molecules, host cells into which the expression vectors have been introduced, and nonhuman transgenic animals in which a 57658 gene has been introduced or disrupted. The invention still further provides isolated 57658 proteins, fusion proteins, antigenic peptides and anti-57658 antibodies. Diagnostic methods utilizing compositions of the invention are also provided.
