ABSTRACT:
A human infant formula sufficient to meet the nutritional requirements of a human infant, comprising proteins having substantially the same amino acid sequence and biological properties as human alpha-lactalbumin and human beta-casein. The proteins may be produced from microorganisms, particularly E. coli. A recombinant DNA segment comprising a human milk protein encoding gene; a promoter sequence directing the transcription of the gene, where the promoter sequence is different from the promoter sequence for the gene in the human organism; and a terminator site for the human milk protein encoding gene. A microorganism containing a recombinant DNA segment comprising a human milk protein encoding gene; a promoter sequence directing the transcription of the gene; and a terminator site for the gene.
