ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Correlation between Neopterin, Biopterin and Nitrite/Nitrate in Cerebrospinal Fluid in Child Patients with Neurological Diseases

Pteridines, 2003
Cerebrospinal fluid (CSF) neopterin been previously reported in various diseases. In this study CSF neopterin, biopterin, and nitrite/nitrate (NOx) Contents were measured and the correlation between them in child patients with various kinds of ...

Influence of an Aromatic Amino Acid Decarboxylase Inhibitor on GTP Cyclohydrolase I Activity in the Rat Brain

Pteridines, 1997
Based on the hypothesis that catecholamine decreases may cause increases in biopterin, we measured the GTP cyclohydrolase I(GTPCH-I) activity and biopterin content in the cerebral cortex, midbrain/diencephalon, cerebeilum, pons/medulla oblongata ...

An Enzyme Immunoassay for Neopterin and Biopterin Using a Microtitre Plate Linked with N2-(3-Aminopropyl) Derivatives of Pteridines

Pteridines, 1990
A novel and sensitive enzyme immunoassay for neopterin and biopterin using a microtitre plate has been developed. The antiserum against neopterin or biopterin was incubated with samples prepared from human urine or rat tissues, and was placed in a well ...

Usefulness of serum biopterin as a predictive biomarker for childhood asthma control: A prospective cohort study

Allergology International, 2019
Background: Pteridines are metabolites of tetrahydrobiopterin, which serves as co-enzyme of nitric oxide synthase. We sought to investigate the usefulness of pteridines as biomarkers for childhood asthma control.

Disorders of biopterin metabolism [PDF]

Journal of Inherited Metabolic Disease, 2009
SummaryDefects in the metabolism or regeneration of tetrahydrobiopterin (BH4) were initially discovered in patients with hyperphenylalaninaemia who had progressive neurological deterioration despite optimal metabolic control (malignant hyperphenylalaninaemia).

Plasma Levels of Neopterin and Biopterin in the Umbilical Vessels and the Maternal Vein

Pteridines, 2003
Tetrahydrobiopterin (BH4) is a highly bioactive pterin required for nitric oxide synthase and monooxygenases of aromatic amino acids, and is involved in the synthesis of nitric oxide, catecholamines and Serotonin.
