    摘要: The invention relates to polypeptide conjugates comprising a polypeptide exhibiting G-CSF activity and having an amino acid sequence that differs from the amino acid sequence of human G-CSF in at least one specified introduced and/or removed amino acid residue comprising an attachment group for a non-polypeptide moiety, and having at least one non-polypeptide moiety attached to an attachment group of the polypeptide. The attachment group may e.g., be a lysine, cysteine, aspartic acid or glutamic acid residue or a glycosylation site, and the non-polypeptide moiety may e.g., be a polymer such as polyethylene glycol or an oligosaccharide. The conjugate has one or more improved properties such as increased biological half-life and reduced side effects.

    摘要: A recombinant microbial cell comprises at least one increased expressible enzyme activity controlling anabolic metabolism of ammonia as a nutrient source, the increased enzyme activity being an NADH-dependent activity catalysing the reaction (a) 2-oxoglutarate+NH3+NADH→glutamate+NAD or being an activity catalysing the reaction (b) 2-oxoglutarate+glutamine+NADH→2 glutamate+NAD or being an activity catalysing the reaction (c) glutamate+NH3+ATP→glutamine+ADP+Pi. The increased enzyme activity is encoded by a nucleic acid coding sequence linked to an expression signal not natively associated with the nucleic acid coding sequence and is increased as compared to the expression of the enzyme activity when the nucleic acid coding sequence is associated with its native expression signal.
