Characterization of the Ornithine Hydroxylation Step in Albachelin Biosynthesis

open access: yesMolecules, 2017
N-Hydroxylating monooxygenases (NMOs) are involved in siderophore biosynthesis. Siderophores are high affinity iron chelators composed of catechol and hydroxamate functional groups that are synthesized and secreted by microorganisms and plants. Recently,

Properties of catechol oxidase from the snow crab.

open access: yesNIPPON SUISAN GAKKAISHI, 1981
A catechol oxidase (EC 1.10.3.1) was extracted from the gills of the snow crab, Chionoecetes opilio, and purified by ammonium sulfate fractionation, ion exchange chromatography on DEAE-cellulose, and gel filtration on Sepharose 6B. Two active components (E-I and E-II) were obtained.

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

open access: yesAllergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Prediction of schizophrenia using MAOA-uVNTR polymorphism: A case–control study

open access: yesIndian Journal of Psychiatry, 2020
Context: Schizophrenia has been associated with disorder of the dopamine system, which is downregulated by projections of the serotonin pathway. Dopamine and serotonin levels are regulated by a system of transporters and enzymes.
