PROCESS FOR THE PREPARATION OF NOVEL PEPTIDES HAVING AN AMINO ACID SEQUENCE AS DERIVED FROM THE AMINO ACID SEQUENCE OF THE HUMAN GRANULOCYTE COLONY STIMULATING FACTOR (HG-CSF)POLYPEPTIDE

摘要

Novel hG-CSF polypeptide derivatives having an amino acid sequence derived from the amino acid sequence of the human granulocyte colony stimulating factor polypeptide by substitution of at least one amino acid by a different aminoacid and/or deletion of at least one amino acid, recombinant plasmids containing a DNA fragment insert coding for any of these hG-CSF polypeptide derivatives, microorganisms carrying one of such plasmids, and methods of producing the hG-CSF polypeptide derivatives using the microorganisms are described.
