Aminopeptidase C of Aspergillus niger is a Novel Phenylalanine Aminopeptidase [PDF]

, 2003
A novel enzyme with a specific phenylalanine aminopeptidase activity (ApsC) from Aspergillus niger (CBS 120.49) has been characterized. The derived amino acid sequence is not similar to any previously characterized aminopeptidase sequence but does share ...

Combining metabolite doping and metabolic engineering to improve 2-phenylethanol production by engineered cyanobacteria

Frontiers in Bioengineering and Biotechnology, 2022
2-Phenylethanol (2-PE) is a rose-scented aromatic compound, with broad application in cosmetic, pharmaceutical, food and beverage industries. Many plants naturally synthesize 2-PE via Shikimate Pathway, but its extraction is expensive and low-yielding ...

High phenylalanine concentrations induce demyelination and microglial activation in mouse cerebellar organotypic slices

Frontiers in Neuroscience, 2022
Phenylketonuria (PKU) is an inborn error of metabolism. Mutations in the enzyme phenylalanine hydroxylase (PAH)-encoding gene lead to a decreased metabolism of the amino acid phenylalanine (Phe).

Prospects for Cell-Directed Curative Therapy of Phenylketonuria (PKU) [PDF]

Molecular Frontiers Journal, 2019
Phenylketonuria (PKU) due to recessively inherited phenylalanine hydroxylase (PAH) deficiency is among the most common inborn errors of metabolism. Dietary therapy begun early in infancy prevents the major manifestations of the disease but shortcomings ...

Polypeptide gels incorporating the exotic functional aromatic amino acid 4-amino-L-phenylalanine [PDF]

, 2018
High-molecular-weight polypeptides with functional aromatic side chains, poly(4-amino-l-phenylalanine), were prepared by the metal-initiated polymerization of the Nα-carboxyanhydride of the corresponding amino acid, which is a microbial derivative of ...
