Abstract: A thrombolytically active composition comprising in combination a modified tissue-type plasminogen activator (t-PA) as a major component and a normal human t-PA, Streptokinase or human urokinase as a minor component in a pharmaceutically acceptable excipient;a method of treating a thrombotic disorder; anda medicinal kit or package for use in treating thrombotic disorders.

Abstract: A process for expressing proteins in Gram(-) bacteria and providing for extracellular secretion thereof, comprising the steps: a) introducing into a Gram(-) bacterium a recombinant DNA construction comprising a promoter, a signal sequence enabling translocation and processing, and a structural gene encoding the desired protein to be expressed; b) cultivating the bacterium under conditions resulting in filamentous growth; and c) recovering the extracellularly secreted protein; a recombinant DNA construction comprising:a promoter, a signal sequence and a structural gene including a cleavage region,wherein the structural gene is of the formula:(E).sub.n (B).sub.m -Y,where n is an integer .gtoreq.

Abstract: A recombinant DNA fragment (Z) coding for an immunoglobulin G binding domain related to staphylococcal protein A. The methionine codon of the recombinant DNA fragment has been replaced with a codon of an amino acid residue other than methionine to enable expression of a methionine-free protein. The present invention is also directed to recombinant DNA sequence containing such recombinant DNAS fragment (Z) as well as a recombinant DNA molecule, plasmid vector and bacterial cell containing such recombinant DNAS fragment. Also disclosed is a process for cleaving a fused protein expressed in a biological system using said recombinant DNA fragment.

Abstract: A polypeptide having bactericidal activity, particularly against gram-negative bacteria, has been isolated from pig intestine. The porcine cecropin has the amino acid sequence: H.sub.2 N-Ser-Trp-Leu-Ser-Lys-Thr-Ala-Lys-Lys-Leu-Glu-Asn-Ser-AlaLys-Lys-Arg-Ile-S er-Glu-Gly-Ile-Ala-Ile-Ala-Ile-Gln-Gly-Gly-Pro-Arg-COOh. Pharmaceutical compositions containing such poypeptides, or functional derivatives thereof, are useful in therapeutic and prophylactic methods for inhibiting bacterial growth.

Abstract: A mammal intestinal hormone precursor having the following peptide structure: His-Ser-Asp-Gly-Thr-Phe-Thr-Ser-Glu-Leu-Ser-Arg-Leu-Arg-L-M-Ala-Arg-Leu-Gl n -Arg-Leu-Leu-Gln-Gly-Leu-Val-Gly-N-O, wherein L is Glu or Asp, M is Gly or Ser, and N and O are selected from Lys and Arg; compositions containing such precursor and a method of stimulating pancreatic secretion.

Abstract: A human intestinal hormone having the following peptide structure: His-Ser-Asp-Gly-Thr-Phe-Thr-Ser-Glu-Leu-Ser-Arg-Leu-Arg-Glu-Gly-Ala-Arg-Le u-Gln-Arg-Leu-Gln-Gly-Leu-Val-NH.sub. 2 ; compositions containing such hormone; and a method of stimulating pancreatic secretion.

Abstract: A non-lysozyme highly active bacteriolytic protein which is heat stable and has a relatively low molecular weight. The protein may be produced by immunizing an insect against E. coli and recovering the protein from the insect. The protein is useful for extracting proteins from genetically engineered bacteria and as a pharmaceutical for inhibiting certain bacteria.
