Synthetic molecule of casein nature, rich in methionine and process for producing it on an industrial scale

摘要

The synthetic molecule according to the invention is characterised in that it is of casein nature and in that it is enriched in methionine. It comprises the following amino acid sequence: IMAGE The invention also relates to the process for producing such molecules characterised in that methionine codons are biologically inserted into the deoxyribonucleic acid chain containing the sequence of a casein fragment, in that the chain obtained is combined with the deoxyribonucleic acid chain of the plasmid of the bacteria Escherichia coli, a Gram-negative bacillus, in order to recombine the germ plasm of these bacteria, in that the latter are then placed in media conditions suitable for their multiplication so as to obtain the cloning of the recombinant deoxyribonucleic acid molecule, and in that after freeze-drying, amounts intended for incorporation into animal feeds then are packaged.
