    摘要: Modified 19kd and 22kd zeins containing lysine are provided. Lysine additions are made by modifying structural genes which encode 19kd and 22kd pre-zeins. Modified zeins produced from the modified structural gene templates are found to retain important properties of unmodified zeins, having similar molecular weights, having the ability to form protein bodies within the rough endoplasmic reticulum of a host cell and being soluble in alcohol.

    摘要: Peptide analogues of insulin-like growth factor 1 and growth factor 2 are disclosed. When the analogue is an analogue of growth factor 1 the glutamic acid residue is absent from position 3 of the N-terminal and either the glutamic acid residue or the threonine residue adjacent to glutamic acid residue at position 3 is replaced by a different amino acid residue. When the peptide analogue is an analogue of insulin growth factor 2 the glutamic acid residue position 5 is absent. Preferred peptide analogues are disclosed. Methods of use in pharmaceutical and veterinary preparations are described.
