Gene for human epidermal growth factor and synthesis and expression thereof
First Claim
1. DNA of the sequence for human epidermal growth factor comprising ##STR6## encoding for physiologically active human epidermal growth factor, having a promoter-proximal end and a promoter-distal end, wherein the 5'"'"' terminal ATG designates the coding strand and the promoter-proximal end of the sequence.

Abstract
A DNA having a base sequence coding for human epidermal growth factor has been synthesized in blocks, and cloned. Novel recombinant DNA transfer vectors containing said cloned DNA have been constructed. The codon usage of the sequence reflects the codon bias of yeast. The DNA sequence is useful for the large scale synthesis of human epidermal growth factor in yeast cells or microorganisms transformed by said recombinant DNA transfer vectors.
