Nonconventional hydrolytic dehalogenation of 1‐chlorobutane by dehydrated bacteria in a continuous solid–gas biofilter [PDF]

open access: yesBiotechnology and Bioengineering, 2005
AbstractRhodococcus erythropolis NCIMB 13064 and Xanthobacter autotrophicus GJ10 are able to catalyze the conversion of halogenated hydrocarbons to their corresponding alcohols. These strains are attractive biocatalysts for gas phase remediation of polluted gaseous effluents because of their complementary specificity for short or medium and for mono ...

Macroalgal microbiomes unveil a valuable genetic resource for halogen metabolism [PDF]

open access: yesMicrobiome
Background Macroalgae, especially reds (Rhodophyta Division) and browns (Phaeophyta Division), are known for producing various halogenated compounds. Yet, the reasons underlying their production and the fate of these metabolites remain largely unknown ...

dl-2-Haloacid Dehalogenase fromPseudomonas sp. 113 Is a New Class of Dehalogenase Catalyzing Hydrolytic Dehalogenation Not Involving Enzyme-Substrate Ester Intermediate [PDF]

open access: yesJournal of Biological Chemistry, 1999
DL-2-Haloacid dehalogenase from Pseudomonas sp. 113 (DL-DEX 113) catalyzes the hydrolytic dehalogenation of D- and L-2-haloalkanoic acids, producing the corresponding L- and D-2-hydroxyalkanoic acids, respectively. Every halidohydrolase studied so far (L-2-haloacid dehalogenase, haloalkane dehalogenase, and 4-chlorobenzoyl-CoA dehalogenase) has an ...

Identification of Pyrazolidine-3-One Derivatives as a Novel Structural Scaffold for ATP Synthase Inhibitors. [PDF]

open access: yesChemMedChem
Following the discovery of oxadiazin‐5‐ones as partial inhibitors of the ATP synthase, we herein report the synthesis of a library of pyrazolidine‐3‐ones and pyrazol‐3‐ones, designed by reducing the six‐membered N–N heterocycles to five‐membered rings.

Continuous Spectrophotometric Assay for Defluorinase and Dechlorinase Activities With α-Halocarboxylic Acids. [PDF]

open access: yesMicrob Biotechnol
Microbial hydrolytic defluorinases and dechlorinases assayed by coupling the reaction product to NAD‐linked dehydrogenases will facilitate screening for and characterising new and known enzymes. ABSTRACT Many environmental pollutants have a fluorine or chlorine atom on a carbon atom adjacent to a carboxylic acid.

Salt mine microorganisms used for the biotransformation of chlorolactones. [PDF]

open access: yesPLoS ONE, 2018
The aim of the project was to find new catalysts capable of chlorolactone biotransformation. Three bicyclic chlorolactones with structures possessing one or two methyl groups in their cyclohexane ring were subjected to screening biotransformation using ...

Combination of a UPO-Based Epoxidation With a Subsequent Ring-Opening Reaction for the Synthesis of Amino Alcohols. [PDF]

open access: yesChembiochem
The synthesis of aromatic amino alcohols via a combination of an unspecific peroxygenase‐catalysed reaction, oxyfunctionalization, and addition of selected nucleophiles and electrophiles in a highly atom‐efficient manner was investigated. This study presents the design to aim for an atom‐efficient chemo‐enzymatic synthesis route towards aromatic amino ...

Bioremediation of halogenated compounds: comparison of dehalogenating bacteria and improvement of catalyst stability [PDF]

open access: yes, 2006
Five bacterial strains were compared for halogenated compounds conversion in aqueous media. Depending on the strain, the optimal temperature for dehalogenase activity of resting cells varied from 30 to 45 degrees C, while optimal pH raised from 8.4 to 9 ...

Hydrolytic dehalogenation of 4-chlorobenzoic acid by an Acinetobacter sp.

open access: yesThe Journal of General and Applied Microbiology, 1997
Acinetobacter sp. strain ST-1, isolated from garden soil, can mineralize 4-chlorobenzoic acid (4-CBA). The bacterium degrades 4-CBA, starting with dehalogenation to yield 4-hydroxybenzoic acid (4-HBA) under both aerobic and anaerobic conditions, suggesting that the dehalogenating enzyme in the strain is not an oxygenase; the enzyme may catalyze halide ...
