Biocatalytic hydroxylation of n-butane with in situ cofactor regeneration at low temperature and under normal pressure

Beilstein Journal of Organic Chemistry, 2012
The hydroxylation of n-alkanes, which proceeds in the presence of a P450-monooxygenase advantageously at temperatures significantly below room temperature, is described.

A Chaperone Complex Formed by HSP47, FKBP65, and BiP Modulates Telopeptide Lysyl Hydroxylation of Type I Procollagen

Journal of Bone and Mineral Research, 2017
Lysine hydroxylation of type I collagen telopeptides varies from tissue to tissue, and these distinct hydroxylation patterns modulate collagen cross‐linking to generate a unique extracellular matrix.

Efficient regio- and stereoselective access to novel fluorinated β-aminocyclohexanecarboxylates

Beilstein Journal of Organic Chemistry, 2013
A regio- and stereoselective method has been developed for the synthesis of novel fluorinated 2-aminocyclohexanecarboxylic acid derivatives with the fluorine attached to position 4 of the ring.

Adenylosuccinate lyase hydroxylation contributes to triple negative breast cancer via the activation of cMYC

Molecular & Cellular Oncology, 2020
Hydroxylation is a post-translational modification affecting protein stability, activity or interactome. We identified adenylosuccinate lyase (ADSL) as a novel hydroxylation substrate in triple negative breast cancer. Hydroxylation affects ADSL enzymatic

A Systematic Account on Aromatic Hydroxylation by a Cytochrome P450 Model Compound I: A Low-Pressure Mass Spectrometry and Computational Study.

Chemistry, 2016
Cytochrome P450 enzymes are heme-containing mono-oxygenases that mainly react through oxygen-atom transfer. Specific features of substrate and oxidant that determine the reaction rate constant for oxygen atom transfer are still poorly understood and ...

Mechanism of Efficient Smithsonite Flotation with a Ternary Composite Collector Under Sulfur-Free Conditions

Molecules
The increasing demand for zinc resources and the declining availability of sulfide zinc ore reserves have made the efficient utilization of zinc oxide a topic of considerable interest. In this study, a ternary composite collector ABN (Al-BHA-NaOL system)

Protein Hydroxylation Catalyzed by 2-Oxoglutarate-dependent Oxygenases*

Journal of Biological Chemistry, 2015
The post-translational hydroxylation of prolyl and lysyl residues, as catalyzed by 2-oxoglutarate (2OG)-dependent oxygenases, was first identified in collagen biosynthesis.

Variability monitoring of the hydroxyl maser emission in G12.889+0.489 [PDF]

, 2012
Through a series of observations with the Australia Telescope Compact Array we have monitored the variability of ground-state hydroxyl maser emission from G12.889+0.489 in all four Stokes polarisation products. These observations were motivated by the known periodicity in the associated 6.7-GHz methanol maser emission.

The Hydroxyl-Water Megamaser Connection. I. Water Emission Toward OH Megamaser Hosts [PDF]

, 2015
Questions surround the connection of luminous extragalactic masers to galactic processes. The observation that water and hydroxyl megamasers rarely coexist in the same galaxy has given rise to a hypothesis that the two species appear in different phases of nuclear activity.
