    摘要: Le procédé assisté par ordinateur permet la construction d'une chaîne de polypeptides ayant une conformation sensiblement prédéterminée (2110). De préférence, une structure de polypeptide bien topographiée, stable et connue, est utilisée comme point de départ (2120), et des unités de peptides aditionnelles sont ajoutées (2140) tout en conservant les contributions enthalpiques et antropiques favorables à la stabilité (2160). De préférence, une librairie de blocs d'oligopeptides est utilisée pour fournir des candidats aux unités de peptides additionnelles. De préférence, la librairie comprend de nombreux paramètres précalculés par ordinateur pour chacun des blocs, p. ex. des paramètres pour estimer les effets énergétiques de variation des paramètres de conformation.

    摘要: A method and vectors for high level expression of genes in bacteria are disclosed. According to one aspect, the present invention provides a method for expressing a gene coding for a desired protein in a bacterium at elevated levels of expression, which comprises ligating at a site adjacent to the translation termination codon of a structural gene for the desired protein, a terminal mRNA sequence from a gene coding for a stable mRNA coding for a bacterial protein; situating the ligated gene so formed in a vector that is replicable in the bacterium such that the gene is operably linked to a transcription promoter; transforming the bacterium with the vector containing the gene; and expressing the gene in the transformed bacterium.

    摘要: A protein which reacts with an antibody to human serum albumin (HSA) can be synthesized in a Bacillus host and secreted therefrom. A Bacillus host is transformed with an expression vector comprising a structural gene which encodes HSA fused in correct reading frame, either directly or via a linker sequence, to the expression elements and signal sequence coding region of a gene that can be recognized by the transcription and translation systems of the host, such that said expression elements control the expression of the HSA- encoding sequence. The transformed strain is grown in a culture medium and subjected to conditions under which the gene fusion is expressed. The resultant protein can be secreted from the Bacillus host into the culture medium.

    摘要: Mutant microbial strains, which are capable of overproducing phenylalanine ammonia-lyase and are useful for the production of L-phenylalanine, may be selected by growing cells on a minimal nutritional medium containing, as substantially the sole carbon source, a phenylalanine analogue, said phenylalanine analogue being a substrate for PAL and the PAL-catalyzed breakdown of said phenylalanine analogue being the rate-determining step for its.overall metabolism.

    摘要: Des souches de bacillus ayant des niveaux réduits de protéase extracellulaire sont produites en remplaçant la séquence chromosomatique originelle d'ADN comprenant le gène pour la protéase extracellulaire, telle que la subtilisine, par une séquence d'ADN partiellement homologue dans laquelle est inséré un segment désactivant d'ADN. Ces souches sont utiles comme hôtes pour l'expression et la sécrétion de polypeptides ou de protéines hétérologues.
