Phenylketonuria is an autosomal recessive disorder caused by a deficiency of phenylalanine hydroxylase. Transthyretin has been implicated as an indicator of nutritional status in phenylketonuria patients. In this study, we report that phenylalanine and its metabolite, phenylpyruvic acid, affect MAPK...

We discovered the phenyllactate (PLA)-producing fungal strain Wickerhamia fluorescens TK1 and purified phenylpyruvate reductase (PPR) from fungal cell-free extracts. The PPR used both NADPH and NADH as cofactors with more preference for the former. The enzyme reaction as well as...

Phenylketonuria is a recessive autosomal disorder that is caused by a deficiency in the activity of phenylalanine-4-hydroxylase, which converts phenylalanine to tyrosine, leading to the accumulation of phenylalanine and its metabolites phenyllactic acid, phenylacetic acid, and phenylpyruvic acid in the...
