Abstract
A DNA molecule coding for a food protein, such as ovalbumin or casein, modified so that the codons for phenylalanine have been omitted or replaced by codons for one or more other metabolisable amino acids. Also a modified edible protein coded for by such a DNA molecule. Such modified proteins are useful in the nutrition of patients suffering from phenylketonuria.
