Details for Patent: 5,679,552

Title: Process for preparing a desired protein
Abstract:A desired protein having the formula: wherein a) A is Lys or Arg, and B and C are arbitrary amino acids, or b) A is an arbitrary amino acid different from Pro, Lys and Arg, and B and/or C is Pro, is produced from a biosynthetically formed amino acid extended protein having the formula: wherein A, B, C and P are as defined above, and X is an amino acid sequence with an even number of amino acids, of which the first one, seen from the N-terminal end, is different from Lys and Arg, all other uneven amino acids are different from Pro, Lys and Arg, and all even amino acids are different from Pro, by reaction with the enzyme dipeptidyl aminopeptidase (DAP I). The desired protein is obtained in a pure state. Thus, e.g. hGH without content of Met-hGH may be produced by the process.
Inventor(s): Dalb.o slashed.ge; Henrik (Virum, DK), Pedersen; John (Kokkedal, DK), Christensen; Thorkild (Aller.o slashed.d, DK), Ringsted; J.o slashed.rli Winnie (Br.o slashed.ndby, DK), Jessen; Torben Ehlern (Holbaek, DK)
Assignee: Novo Nordisk A/S (DK)
Filing Date:May 25, 1995
Application Number:08/450,837
Claims:1. An isolated nucleic acid sequence encoding an amino-terminal extended human growth hormone of the formula:

X-human growth hormone wherein X is a charged amino acid sequence having at least 2 amino acids and wherein the N-terminal amino acid of X is other than Lys and Arg, and wherein all other uneven numbered amino acids are other than Pro, Lys and Arg, and wherein all even numbered amino acids are other than Pro, and wherein at least one amino acid in amino acid sequence X is a charged amino acid.

2. The isolated nucleic acid sequence according to claim 1 wherein X comprises an even number of amino acids.

3. The isolated nucleic acid sequence according to claim 1 wherein the C-terminal amino acid of X is a charged amino acid.

4. The isolated nucleic acid sequence according to claim 1 wherein the amino acid sequence X comprises 4 amino acids.

5. The isolated nucleic acid sequence according to claim 1 wherein the amino acid sequence X comprises 2 amino acids.

6. The isolated nucleic acid sequence according to claim 1 wherein the amino acid sequence X is Met-Glu-Ala-Glu.

7. The isolated nucleic acid sequence according to claim 1 wherein the amino acid sequence X is Met-Phe-Glu-Glu.

8. The isolated nucleic acid sequence according to claim 1 wherein the amino acid sequence X is Met-Thr-Glu-Glu.

9. The isolated nucleic acid sequence according to claim 1 wherein the amino acid sequence X is Met-Glu-Glu-Glu.

10. The isolated nucleic acid sequence according to claim 1 wherein the amino acid sequence X is Ala-Ala-Glu-Glu.

11. The isolated nucleic acid sequence according to claim 1 wherein the N-terminal amino acid of X is Met.

12. The isolated nucleic acid sequence according to claim 1 wherein the C-terminal amino acid of X is Glu or Asp.

13. The isolated nucleic acid sequence according to claim 1 wherein the amino acid sequence X is Ala-Glu.

14. A recombinant vector comprising the nucleic acid sequence of claim 1.

15. A bacterial cell comprising the recombinant vector of claim 1.
