    摘要: This invention relates to a novel physiologically active polypeptide containing modified amino acids on both terminals at the amino-terminus and the carboxy-terminus in the amino acid sequence of the human tumor neclosis factor (human TNF), a recombinant plasmid containing a DNA region encoding the polypeptide, a recombinant microorganism cell transformed with the recombinant plasmid, a method of producing the polypeptide by cultivating the microorganism cell, a pharmaceutical composition containing the polypeptide and a method of purifying and recovering the polypeptide. The polypeptide in this invention has excellent antitumor activity compared to the human TNF and can be utilized as an active ingredient of a pharmaceutical composition having antitumor activity.
