Structural basis for endoperoxide-forming oxygenases

Beilstein Journal of Organic Chemistry, 2022
Endoperoxide natural products are widely distributed in nature and exhibit various biological activities. Due to their chemical features, endoperoxide and endoperoxide-derived secondary metabolites have attracted keen attention in the field of natural ...

Métabolisme oxygéné des acides gras polyinsaturés et fonction dans les cellules sanguines et vasculaires1

Oléagineux, Corps gras, Lipides, 2011
Most polyunsaturated fatty acids have the minimal 1,4-cis,cis-pentadiene configuration to be oxygenated into a conjugated diene hydroperoxide. This product is usually reduced into the corresponding hydroxy derivative by cell glutathione peroxidases.

OxDBase: a database of oxygenases involved in biodegradation

BMC Research Notes, 2009
Background Oxygenases belong to the oxidoreductive group of enzymes (E.C. Class 1), which oxidize the substrates by transferring oxygen from molecular oxygen (O2) and utilize FAD/NADH/NADPH as the co-substrate.

Sudestada1, a Drosophila ribosomal prolyl-hydroxylase required for mRNA translation, cell homeostasis, and organ growth [PDF]

, 2014
Genome sequences predict the presence of many 2-oxoglutarate (2OG)-dependent oxygenases of unknown biochemical and biological functions in Drosophila. Ribosomal protein hydroxylation is emerging as an important 2OG oxygenase catalyzed pathway, but its ...

Oxygenases for oxygen sensing [PDF]

Pure and Applied Chemistry, 2008
Abstract In animals, cellular and physiological responses to oxygen level variations are regulated via the post-translational modification of the heterodimeric hypoxia-inducible transcription factor (HIF). Hydroxylation of the HIF-α subunit at either of two conserved prolyl residues enables binding to the von Hippel-Lindau protein (pVHL)

Identification of a Phylogenetically Divergent Vanillate O-Demethylase from Rhodococcus ruber R1 Supporting Growth on Meta-Methoxylated Aromatic Acids

Microorganisms, 2022
Rieske-type two-component vanillate O-demethylases (VanODs) catalyze conversion of the lignin-derived monomer vanillate into protocatechuate in several bacterial species. Currently, VanODs have received attention because of the demand of effective lignin

Bacillus subtilis HmoB is a heme oxygenase with a novel structure [PDF]

BMB Reports, 2012
Iron availability is limited in the environment and mostbacteria have developed a system to acquire iron from hosthemoproteins. Heme oxygenase plays an important role bydegrading heme group and releasing the essential nutrientiron.

Chlamydomonas reinhardtii LFO1 Is an IsdG Family Heme Oxygenase

mSphere, 2017
Heme is essential for respiration across all domains of life. However, heme accumulation can lead to toxicity if cells are unable to either degrade or export heme or its toxic by-products.

Molecular insights into the unusually promiscuous and catalytically versatile Fe(II)/α-ketoglutarate-dependent oxygenase SptF

Nature Communications, 2022
Non-heme iron and α-ketoglutarate-dependent (Fe/αKG) oxygenases have attracted attention for their application as biocatalysts due to their flexibility and high efficiency.
