Transcriptional analysis of pqqD and study of the regulation of pyrroloquinoline quinone biosynthesis in Methylobacterium extorquens AM1 [PDF]

open access: yes, 1995
Methanol dehydrogenase, the enzyme that oxidizes methanol to formaldehyde in gram-negative methylotrophs, contains the prosthetic group pyrroloquinoline quinone (PQQ).

ALKBH1 is an RNA dioxygenase responsible for cytoplasmic and mitochondrial tRNA modifications

open access: yesNucleic Acids Research, 2017
ALKBH1 is a 2-oxoglutarate- and Fe2+-dependent dioxygenase responsible for multiple cellular functions. Here, we show that ALKBH1 is involved in biogenesis of 5-hydroxymethyl-2΄-O-methylcytidine (hm5Cm) and 5-formyl-2΄-O-methylcytidine (f5Cm) at the ...

The Cysteine Dioxygenase Homologue from Pseudomonas aeruginosa Is a 3-Mercaptopropionate Dioxygenase [PDF]

open access: hybridJournal of Biological Chemistry, 2015
Background: Thiol dioxygenation is catalyzed by enzymes specific for each substrate. Results: Kinetic, structural, and spectroscopic data describe an enzyme from P. aeruginosa that is a 3-mercaptopropionate dioxygenase with secondary cysteine dioxygenase

Evolution of l‐DOPA 4,5‐dioxygenase activity allows for recurrent specialisation to betalain pigmentation in Caryophyllales

open access: yesNew Phytologist, 2019
Summary The evolution of l‐DOPA 4,5‐dioxygenase activity, encoded by the gene DODA, was a key step in the origin of betalain biosynthesis in Caryophyllales.

Mechanistic Insight into the Enzymatic Reduction of Truncated Hemoglobin N of Mycobacterium tuberculosis: role of the CD loop and pre-A Motif in electron cycling [PDF]

open access: yes, 2014
Background: The HbN of Mycobacterium tuberculosis carries a potent nitric-oxide dioxygenase activity despite lacking a reductase domain. Results: The NADH-ferredoxin reductase system acts as an efficient partner for the reduction of HbN.

Indoleamine 2,3-dioxygenase vaccination [PDF]

open access: yesOncoImmunology, 2015
Indoleamine 2,3-dioxygenase (IDO) is an immunoregulatory enzyme. Remarkably, we discovered IDO-specific T cells that can influence adaptive immune reactions in patients with cancer. Further, a recent phase I clinical trial demonstrated long-lasting disease stabilization without toxicity in patients with non-small-cell lung cancer (NSCLC) who were ...

Structural insights into substrate and inhibitor binding sites in human indoleamine 2,3-dioxygenase 1

open access: yesNature Communications, 2017
Human indoleamine 2,3-dioxygenase 1 (hIDO1) is an attractive cancer immunotherapeutic target owing to its role in promoting tumoral immune escape. However, drug development has been hindered by limited structural information.

Insight Into Metabolic Versatility of an Aromatic Compounds-Degrading Arthrobacter sp. YC-RL1

open access: yesFrontiers in Microbiology, 2018
The genus Arthrobacter is ubiquitously distributed in different natural environments. Many xenobiotic-degrading Arthrobacter strains have been isolated and described; however, few have been systematically characterized with regard to multiple ...

Metabolic regulation of regulatory T cell development and function [PDF]

open access: yes, 2014
It is now well established that the effector T cell (Teff) response is regulated by a series of metabolic switches. Quiescent T cells predominantly require ATP-generating processes, whereas proliferating Teff require high metabolic flux through growth ...
