Abstract
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.
