Abstract:
Pour l'obtention d'un ensemble de peptides, polypeptides ou protéines capable de catalyser une séquence de réactions chimiques conduisant à la formation d'au moins un composé désiré, on produit une bibliothèque de gènes au moins partiellement constitués de polynucléotides synthétiques stochastiques, on amplifie ces gènes et on effectue un criblage de façon à identifier une pluralité de gènes capables d'être exprimés sous forme d'un ensemble de peptides, polypeptides ou protéines ayant l'aptitude catalytique désirée, définie ci-dessus. On utilise ensuite l'information génétique ainsi obtenue pour produire en ensemble de peptides, polypeptides ou protéines ayant ladite aptitude catalytique. On peut finalment utiliser cet ensemble pour la production d'un composé chimique, éventuellement nouveau, ayant une propriété donnée.
Abstract:
Methods for the generation of new compounds are disclosed. The present invention eliminates the need to know in advance the structure or chemical composition of a compound having a desired property. The disclosure of the present invention provides that diversity of unknown compounds may be produced by 'random' chemistry, and such a diversity of unknown compounds may be screened for one or more desired properties to detect the presence of suitable compounds. In one aspect, a starting group of organic compounds is caused to undergo a series of chemical reactions to create a diversity of new organic compounds that are screened for the presence of organic compounds having the desired property. In another aspect of the present invention, a diversity of compounds is generated from a group of substrates which are subjected to a group of enzymes representing a diversity of catalytic activities.

Abstract:
Microbiologicale prodn. of peptides or polypeptides (I) comprises first producing, simultaneously in the same medium, many genes (A) composed at least partly of stochastic, synthetic polynucleotides, and introducing these genes into host cells. The (A)-contg. strains are cultured so as to clone (A) and induce expression of proteins coded by (A). The modified strains are screened/selected to identify those which produce the required (I), according to a particular property. These strains are then isolated and cultured to produce (I). In modification, the (A)-contg. transformants are selected for presence of a particular stochastic DNA or RNA sequence, and such sequences recovered from cultures of the appropriate strains.
