Plasmids and aromatic degradation in Sphingomonas for bioremediation : Aromatic ring cleavage genes in soil and rhizosphere [PDF]

open access: yes, 2009
Microbial degradation pathways play a key role in the detoxification and the mineralization of polyaromatic hydrocarbons (PAHs), which are widespread pollutants in soil and constituents of petroleum hydrocarbons.

Biodegradation of paracetamol by Amycolatopsis sp. Poz 14

open access: yesBMC Research Notes
Objective Paracetamol is widely used throughout the world and its high consumption has led to its detection in the environment as an emerging contaminant. In this work, the actinobacterium Amycolatopsis sp.

Vitamin C increases 5-hydroxymethylcytosine level and inhibits the growth of bladder cancer

open access: yesClinical Epigenetics, 2018
Background 5-Hydroxymethylcytosine (5hmC) is converted from 5-methylcytosine (5mC) by a group of enzymes termed ten-eleven translocation (TET) family dioxygenases.

Oxidative inactivation of ring-cleavage extradiol dioxygenases : mechanism and ferredoxin-mediated reactivation [PDF]

open access: yes, 2009
Extradiol dioxygenases are ubiquitous enzymes that catalyze ring cleavage of a wide variety of aromatic compounds. Most of these enzymes contain a ferrous ion at the active site, which is bound to the polypeptide chain through a conserved triad of two ...

Ring-hydroxylating dioxygenases involved in PAH biodegradation : structure, function, biodiversity [PDF]

open access: yes, 2011
International audienceThe first step in the biodegradation of PAHs by aerobic bacteria is catalyzed by metalloenzymes known as ring-hydroxylating dioxygenases (RHDs). Because of the hydrophobic nature and chemical resistance of PAHs, their initial attack
