    • The invention is related to a method for making mature human insulin or an analogue thereof by culturing a fungi cell comprising a DNA sequence encoding a precursor for human insulin or an analogue of human insulin which precursor comprises the B-chain of human insulin or an analogue thereof, the A-chain of human insulin or an analogue thereof and a C-peptide linking the B-chain and the A-chain together thereof, wherein the C-peptide comprises at least one Kex2 cleavage site and an amino acid sequence attached at one end to the C-terminal amino acid residue in the B-chain and at the other end to the Kex2 site which amino acid sequence will facilitate a more efficient Kex2 cleavage within the fungi cell. The C-terminal extension of the B-chain may furthermore be capable of subsequently being cleaved off from the C-terminal amino acid residue in the B-chain by means of a carboxypeptidase activity either within the fungi cell or subsequently in the culture medium.
    • 本发明涉及通过培养包含编码人胰岛素前体的DNA序列或人胰岛素类似物的真菌细胞来制备成熟人胰岛素或其类似物的方法,该前体包含人胰岛素的B链或类似物 其中,人胰岛素的A链或其类似物和将β-链和A链连接在一起的C-肽,其中所述C-肽包含至少一个Kex2切割位点和附着于其上的氨基酸序列 一端到B链中的C-末端氨基酸残基,另一端连接到Kex2位点,该氨基酸序列将促进真菌细胞内的更有效的Kex2切割。 B链的C-末端延伸还可以随后通过真菌细胞内或随后在培养基中的羧肽酶活性随后从B链中的C末端氨基酸残基断裂。

    • The present invention relates to human insulin derivatives having a protracted profile of action in which the A21 and B3 amino acid residues are, independently, any amino acid residue which can be coded for by the genetic code except Lys, Arg and Cys; Phe.sup.B1 may be deleted; the B30 amino acid residue is (a) a non-codable, lipophilic amino acid having from 10 to 24 carbon atoms in which case an acyl group of a carboxylic acid with up to 5 carbon atoms is bound to the E-amino group of Lys.sup.B29 ; (b) any amino acid residue which can be coded by the genetic code except Lys, Arg and Cys, in which case a lipophilic substituent is bound to the E-amino group of Lys.sup.B29 ; or (c) deleted, in which case a lipophilic substituent is bound to the E-amino group of LyS.sup.B29 ; and any Zn.sup.2+ complexes thereof; provided that when the B30 amino acid residue is Thr or Ala, the A21 and B3 amino acid residues are both Asn and Phe.sup.B1 is present, then the insulin derivative is a Zn.sup.2 + complex.
    • 本发明涉及具有延长的作用曲线的人胰岛素衍生物,其中A21和B3氨基酸残基独立地是可由除Lys,Arg和Cys之外的遗传密码编码的任何氨基酸残基; PheB1可能被删除; B30氨基酸残基是(a)具有10-24个碳原子的非可编码的亲脂性氨基酸,在这种情况下,具有至多5个碳原子的羧酸的酰基与LysB29的E-氨基结合 ; (b)除了Lys,Arg和Cys之外可以通过遗传密码编码的任何氨基酸残基,在这种情况下,亲油性取代基与LysB29的E氨基结合; 或(c)缺失,在这种情况下,亲油取代基与LySB29的E氨基结合; 及其任何Zn2 +配合物; 条件是当B30氨基酸残基是Thr或Ala时,A21和B3氨基酸残基都是Asn和PheB1,则胰岛素衍生物是Zn 2+络合物。
