Phenylketonuria (PKU) is a genetically inherited disease where the body fails to convert Phenylalanine (Phe) to Tyrosine (Tyr) due to the defective Phenylalanine Hydroxylase (PAH) enzyme, resulting in the elevated blood Phe level causing neurological damage. Of all therapies, Large Neutral Amino Acid (LNAA) supplementation has become a promising approach to the dietary treatment of PKU, where the LNAA compete with Phe for the same L-Type Large Neutral Amino Acid Transporter (LAT1, SLC7A5) across the blood-brain barrier, decreasing brain Phe level. In this study we have designed an easily digestible protein enriched with LNAA (except Phe), using bovine αs1 casein as template by homology modeling. Our challenge was to maximize the LNAAs (except Phe) in the protein model by finding a suitable scaffold for hosting LNAAs, thereby turning the usual concept of homology modeling. Bioinf.. View More»
