A new inhibitor of decarboxylase of aromatic amino acids

Experientia, 1962
N-(DL-Seryl)-N′-(2,3,4-trihydroxybenzyl)hydrazin (Ro 4-4602) bewriktin vitro starke Hemmung der Decarboxylase, die durch Pyridoxal-5′-phosphat nicht und durch Dialyse nur wenig vermindert werden kann. Nach i.p. Applikation der Substanz kommt es zu starker Verminderung der Decarboxylase-Aktivitat und zu massiger Herabsetzung von 5-Hydroxytryptamin und ...

Retinoblastoma Aqueous Humor: Aromatic Amino Acids

Ophthalmic Paediatrics and Genetics, 1993
Aqueous humor from children with retinoblastoma obtained at enucleation and from eyes with adult cataracts were assayed with electrochemical liquid chromatography (Model 5500 Coulochem electrode array system) for metabolites of tyrosine, tryptophan metabolic pathways, catecholamine degradation pathways and ascorbate.

PHOTOLYSIS OF CYSTINE IN THE PRESENCE OF AROMATIC AMINO ACIDS

Photochemistry and Photobiology, 1968
ResumenSe dan evidencias para explicar los distintos rendimientos cuánticos de fotólisis con lux u.v. para distintos residuos de cisteina en lisozima e insulina. En sistemas modelos de mezclas de aminoácidos, el aminoácido triptofano muestra un marcado aumento en el rendimiento cuántico en la fotólisis de la cisteina.

Aromatic Amino Acid Biosynthesis

1982
The inhibition of aromatic amino acid biosynthesis has early been recognized as a possible herbicidal target because this biosynthetic pathway occurs only in microorganisms and plants but not in animals. In a study on the inhibition of shikimate dehydrogenase — the enzyme responsible for the synthesis of the intermediate shikimic acid (Scheme 1 ...

The aromatic amino acid hydroxylases.

Advances in enzymology and related areas of molecular biology, 2000
The enzymes phenylalanine hydroxylase, tyrosine hydroxylase, and tryptophan hydroxylase constitute the family of pterin-dependent aromatic amino acid hydroxylases. Each enzyme catalyzes the hydroxylation of the aromatic side chain of its respective amino acid substrate using molecular oxygen and a tetrahydropterin as substrates.
