The rate of activation of plasminogen by tissue-type plasminogen activator (t-PA) is greatly increased by fibrin, but much less by fibrinogen. Fibrin(ogen) fragments such as the fibrin(ogen) cyanogen bromide fragment FCB-2 and FCB-5, and a synthetic peptide with the sequence of fibrinogen A alpha-(148-160), a constituent of FCB-2, also have rate...

Fibrin accelerates the activation of plasminogen catalyzed by tissue-type plasminogen activator much stronger than fibrinogen. Detailed studies showed that (part of) this rate-enhancing effect of fibrin is brought about by two sites in the fibrin molecule: one in Aα-(148-160) and one in the γ-chain stretch 311-379 (also known as FCB-5). During...

The sequence fibrinogen-Aα-(148-160) can mimic part of the fibrin-induced rate enhancement of the activation of plasminogen by tissue-type plasminogen activator. Previously we have reported that the lysine residue at position Aα-157 is crucial. During our further investigations on Aα-157 we found that lysine at position Aα-157 may be replaced by...

Recent studies suggest that plasminogen activators not only hydrolyse a specific arginine-valine bond in plasminogen, but may also cleave other proteins such as fibronectin. We studied the substrate specificity, particularly the preference for arginyl over lysyl peptide bonds, of tissue-type plasminogen activator (t-PA) as well as of two-chain...

The expression in Aspergillus is described of genes, coding for intracellular and extracellular proteins controlled by the promoter region of the constitutively and efficiently expressed glyceraldehyde-3-phosphate dehydrogenase gene (gpdA) of Aspergillus nidulans. Both the homologous gpdA and the heterologous Escherichia coli β-galactosidase ...

The Mpc‐group has a somewhat better stability than the Fmoc‐group, resists catalytic hydrogenolysis, is highly stable in acidic media and its elimination product does not polymerize spontaneously. In a direct comparison of coupling efficiencies obtained in solid phase peptide syntheses using Mpc‐ or Fmoc‐amino acids it is shown that the use of...

Fibrin, not fibrinogen, enhances the rate of tPA catalysed plasminogen activation. In earlier studies we have shown that a site involved in this rate enhancement is located in a tridecapeptide, i.e. fibrinogen A alpha-(148-160). This sequence comprises a special charge distribution in which a stretch with alternating neutral and acidic amino...

To enable preclinical studies on homologous interleukin-3 (IL-3) in primate species, we isolated the gene encoding Rhesus monkey IL-3 (RhIL-3). The nucleotide sequence of the RhIL-3 gene displayed 92.9% homology with that of the human IL-3 (hIL-3) gene. The isolated RhIL-3 gene encodes a 143-amino acid (aa) precursor polypeptide, nine C-terminal...

A comparison was made of the effects of antinutritional factors present in Phaseolus vulgaris on piglets, rats and chickens. Also the hypothesis of whether the negative effect on weight gain due to the inclusion of raw Phaseolus vulgaris in the diet can be attributed to an insufficient supply of amino acids was tested. Test diets containing 200...

The gene coding for benzoate-para-hydroxylase (bphA) of Aspergillus niger was cloned using differential hybridisation techniques and complementation of mutants deficient in this enzyme activity. The nucleotide sequence of the gene was determined, the presence of two introns was shown and the transcription start and termination sites were...

The selectivity of cathepsin D, a mammalian intracellular aspartyl proteinase involved in the degradation of endocytosed proteins, was studied. For this purpose, several proteins of known primary structure were subjected to mild proteolysis by the enzyme, and the preferentially cleaved peptide bonds were identified. Comparison of the primary...

α2-Antiplasmin Enschede is a variant of α2-antiplasmin which has lost its ability to inhibit plasmin irreversibly and which is associated with haemorrhagic disorder [Kluft et al. (1987) J. Clin. Invest. 80, 1391-1400]. The abnormal protein was purified from the plasma of a homozygous patient and subjected to one-dimensional peptide mapping using...

We have determined the nucleotide sequence of the human plasminogen activator inhibitor-1 (PAI-1) gene and significant stretches of DNA which extend into its 5'- and 3'-flanking DNA regions; a total sequence of 15,867 base pairs (bp) is presented. The sequenced 5'-flanking DNA (1,520 bp) contains the essential eukaryotic cis-type proximal...

Two-chain tissue-type plasminogen activator (t-PA), which consists of a heavy chain (M(r) ??? 38,000) and a light chain (M(r) ??? 31,000) connected by a disulfide bridge, was reduced with 2-mercaptoethanol and then air-reoxidized at a low protein concentration and carboxamidomethylated. The two chains were separated by means of zinc chelate...

To investigate the regulation of age-related changes in albumin synthesis in the rat liver, total postnuclear RNA and polyribosomes, both membrane-bound and free, were prepared from livers of rats of different ages. By the use of a specific complementary DNA probe, the albumin mRNA sequence content was quantitated in these RNA fractions. These...

Soy protein is the vegetable protein that is most frequently used in meat products. Accordingly, detection and determination procedures have mainly been focused on soy proteins. Cereal proteins received far less attention analytically, let alone the less conventional vegetable proteins. Every method published has only a limited applicability,...

Rat fibrinogen was purified from rat plasma by using lysine-Sepharose chromatography, repeated precipitation with 25%-satd. (HN4)2SO4 and gel chromatography on Sepharose 6B. To minimize proteolytic activity, rats were injected intravenously with Trasylol before bleeding and the collected blood was treated with Trasylol and di-isopropyl...
