based on the reciprocal comparison of prosomatocrinin with proglucagon and pro ( phm-vip ) , it was assumed that the c-terminal fragment of prosomatocrinin separated from somatocrinin by a single arginine residue is a second glucagon-like peptide in the precursor molecule , which apparently possesses a biological activity .
