Phenylketonuria pathway

WebPhenylketonuria is induced by an error in phenylalanine metabolism, which is due to the lack or dysfunction of phenylalanine hydroxylase, involved in the conversion into tyrosine. By this metabolism, the concentration of phenylalanine in the blood is elevated. WebMicrobial inhibition assay. Circular filter paper is completely saturated with blood. It is then placed in a cultured media streaked with bacillus subtilis. If phenylalanine is in high levels in the blood it will counteract the inhibitor beta-2-thienylalanine in the media.It inhibits the B.subtilius. So a positive test will have growth.
