摘要:
A process for obtaining hirudin derivatives from E. coli secretor mutants which entails:(1) construction of a recombinant vector on which there is located the gene coding for a hirudin derivative directly downstream of a DNA section which codes for a bacterial signal peptide;(2) transformation of an E. coli secretor mutant with the recombinant vector constructed in step (1);(3) cultivation of the transformed cells in a medium; and(4) obtaining the hirudin derivative from the medium; anda recombinant vector which contains one or more copies of a gene construct which codes for a protein consisting of a bacterial signal peptide and of a hirudin derivative, and a hirudin derivative with the N-terminal amino-acid sequence A-(SEQ ID NO: 5) in which A represents Ala, Gln, His, Phe, Tyr, Glu, Ser, Asp or Asn.

The invention is directed to a pharmaceutical composition containing at least one FGF-21 (fibroblast growth factor 21) compound, at least one GLP-1R (glucagon-like peptide-1 receptor) agonist and optionally at least one anti-diabetic drug and/or at least one DPP-4 (dipeptidyl peptidase-4) inhibitor for the treatment of at least one metabolic syndrome and/or atherosclerosis, in particular diabetes, dyslipidemia, obesity and/or adipositas.
摘要:
Pancreatic carboxypeptidase B or an isoform or a mutein of carboxypeptidase B may be prepared by (a) expressing a natural or unnatural enzymatically inactive precursor form of carboxypeptidase B in a microorganism by secretion, (b) purifying the precursor form expressed by secretion, and (c) converting the purified precursor form into the active form by an enzymatic treatment. A nucleic acid construct and a host cell containing the construct are useful for preparing pancreatic carboxypeptidase B or an isoform or a mutein thereof by this method.
