摘要:
The first step in human meningococcal infection involves adhesion to the epithelial cells of the nasopharynx tract. The invention provides various methods and compounds for preventing the attachment of Neisserial cells to epithelial cells and is based on the identification of 347 meningococcal genes which play a role in the adhesion process.
摘要:
In an improved process for the preparation of D-.alpha.-amino acids by the stereoselective conversion of racemic mixtures of 5-substituted hydantoins with an enzymatic system produced by a microorganism, the improvement consists in the fact that a microorganism is used which is transformed with the plasmid pSM700 cultivated at a temperature of between 20.degree. C. and 28.degree. C. The use of this microorganism allows an improvement in the expression of the enzymatic system and an increase in the conversion rate of the racemic hydantoin to D-.alpha.-amino acid.
摘要:
A new plasmid vector is described which can replicate in B. subtilis and which can express and secrete, in the culture medium, human beta interleukin-1 (beta IL-1) without amino acid sequences extraneous to the natural molecule, a strain of B. subtilis transformed by the vector and a method for the expression and secretion of mature human beta interleukin-1. The human beta interleukin-1 thus obtained shows a specific acitvity of 1.times.10.sup.9 U/mg of protein and is particularly suitable as a stimulant for the immune system, as an adjuvant in vaccines for the activation of the repair mechanism in cases of tissue damage, and for the treatment of auto-immune diseases in man.

摘要:
Disclosed is a novel method for the in vivo and in vitro synthesis of modified peptides, using either engineered microorganisms capable of expressing peptide synthetases with modified substrate specificity, or peptide synthetases extracted from said microorganisms.
摘要:
The cloning and sequencing of the gene which codes for a new pilinic subunit of Bordetella pertussis are described. The aminoacid sequence of the mature subunit, deduced from its necleotide sequence, is similar but not identical to that of the known pilins 2, 3 and 6. Polypeptides having the aminoacid sequence of the mature pilinic subunit or of regions thereof are particularly useful for the development of synthetic acellular vaccines against pertussis.
