Polypeptides having growth hormone releasing activity

Abstract

Polypeptides corresponding to growth hormone releasing factor in which methionine at position 27 has been replaced by a leucine residue retain full growth hormone releasing activity. In the case of the full length (44-amino acid) polypepitide, the leucine analog has full biological activity in the free acid form, unlike the natural growth releasing factor which requires carboxy terminal amidation for full biological activity.

Dependencies are inferred from the claim text.
