ChnagG Plays the Role of 5-Salicylate Hydroxylase in the Gentisic Acid Pathway of Salicylic Acid Metabolism in Cochliobolus heterostrophus. [PDF]

Mol Plant Pathol
The ChnagG gene in Cochliobolus heterostrophus encodes 5‐salicylate hydroxylase, converting salicylic acid (SA) to gentisic acid, enhancing pathogenicity and suppressing plant SA signalling‐mediated defences during infection. ABSTRACT Salicylic acid (SA) plays a crucial role in the defence strategies of plants against fungal pathogens.

Bringing up to date the toolkit for the catabolism of aromatic compounds in fungi: The unexpected 1,2,3,5-tetrahydroxybenzene central pathway. [PDF]

Microb Biotechnol
Our understanding of how fungi utilize gallate or other syringyl derivatives is, to date, scarce and mostly relies on unproven assumptions. This study demonstrates the existence of a new 1,2,3,5‐tetrahydroxybenzene central pathway for the catabolism of gallate and related compounds in numerous fungi.

Gentisate pathway in Salmonella typhimurium: metabolism of m-hydroxybenzoate and gentisate [PDF]

FEMS Microbiology Letters, 1992
Salmonella typhimurium was shown to use the gentisate pathway to metabolize m-hydroxybenzoate and gentisate, m-Hydroxybenzoate hydroxylase and gentisate 1,2-dioxygenase were induced by growth on either gentisate or m-hydroxybenzoate. These enzymes were not detected when the bacteria were grown with glucose or glucose and either m-hydroxybenzoate or ...

Expanding Antarctic biogeography: microbial ecology of Antarctic island soils

Ecography, Volume 2023, Issue 9, September 2023., 2023
The majority of islands surrounding the Antarctic continent are poorly characterized in terms of microbial macroecology due to their remote locations, geographical isolation and access difficulties. The 2016/2017 Antarctic Circumnavigation Expedition (ACE) provided unprecedented access to a number of these islands.

Crystal structure of the monocupin ring‐cleaving dioxygenase 5‐nitrosalicylate 1,2‐dioxygenase from Bradyrhizobium sp.

Acta Crystallographica Section D, Volume 79, Issue 7, Page 632-640, July 2023., 2023
The crystal structure of the monocupin 5‐nitrosalicylate 1,2‐dioxygenase, an iron(II)‐dependent ring‐cleaving dioxygenase, from Bradyrhizobium sp. was determined by molecular replacement using a theoretical model obtained by AlphaFold2. Comparison with structures of other members of the same class and docking of the substrate allowed identification of ...

Structural, Spectroscopic, and Electrochemical Properties of Nonheme Fe(II)-Hydroquinonate Complexes: Synthetic Models of Hydroquinone Dioxygenases [PDF]

, 2012
Using the tris(3,5-diphenylpyrazol-1-yl)borate (Ph2Tp) supporting ligand, a series of mono- and dinuclear ferrous complexes containing hydroquinonate (HQate) ligands have been prepared and structurally characterized with X-ray crystallography.

Emerging roles for thiol dioxygenases as oxygen sensors

The FEBS Journal, Volume 289, Issue 18, Page 5426-5439, September 2022., 2022
Thiol dioxygenases (TDOs) catalyse oxidation of thiols to sulphinates. Recent reports identify TDOs which catalyse oxidation of N‐terminal cysteine residues of protein substrates in an O2‐sensitive manner, promoting degradation: N‐terminal cysteinyl dioxygenases (NCOs). These appear to form a separate subclass of TDO from those which catalyse oxidation
