- he disease Phenylketonuria (or PKU) occurs when the enzyme that helps to catalyze the conversion of the amino acid phenylalanine into non-harmful tyrosine is mutated and doesn't work as well (or at all). Phenylalanine will still break down into tyrosine by itself, because this is a favorable reaction. Why is the non-functional enzyme a problem? Explain in a few sentences.
