Homoacetogenesis in Deep-Sea Chloroflexi, as Inferred by Single-Cell Genomics, Provides a Link to Reductive Dehalogenation in Terrestrial Dehalococcoidetes

mBio, 2017
The deep marine subsurface is one of the largest unexplored biospheres on Earth and is widely inhabited by members of the phylum Chloroflexi. In this report, we investigated genomes of single cells obtained from deep-sea sediments of the Peruvian Margin,

Probing the Role of the Conserved Arg174 in Formate Dehydrogenase by Chemical Modification and Site-Directed Mutagenesis

Molecules, 2021
The reactive adenosine derivative, adenosine 5′-O-[S-(4-hydroxy-2,3-dioxobutyl)]-thiophosphate (AMPS-HDB), contains a dicarbonyl group linked to the purine nucleotide at a position equivalent to the pyrophosphate region of NAD+.

Production, characterization and determination of the real catalytic properties of the putative "succinate dehydrogenase" from Wolinella succinogenes [PDF]

, 2009
Both the genomes of the epsilonproteobacteria Wolinella succinogenes and Campylobacter jejuni contain operons (sdhABE) that encode for so far uncharacterized enzyme complexes annotated as ‘non-classical’ succinate:quinone reductases (SQRs).

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Respiratory chain components are required for peptidoglycan recognition protein-induced thiol depletion and killing in Bacillus subtilis and Escherichia coli

Scientific Reports, 2021
Mammalian peptidoglycan recognition proteins (PGRPs or PGLYRPs) kill bacteria through induction of synergistic oxidative, thiol, and metal stress. Tn-seq screening of Bacillus subtilis transposon insertion library revealed that mutants in the shikimate ...

Integration of text mining and biological network analysis: Identification of essential genes in sulfate-reducing bacteria

Frontiers in Microbiology, 2023
The growth and survival of an organism in a particular environment is highly depends on the certain indispensable genes, termed as essential genes. Sulfate-reducing bacteria (SRB) are obligate anaerobes which thrives on sulfate reduction for its energy ...

Kinetics for formate dehydrogenase of Escherichia coli formate-hydrogenlyase

Journal of Biological Chemistry, 1991
Kinetic parameters of the selenium-containing, formate dehydrogenase component of the Escherichia coli formate-hydrogenlyase complex have been determined with purified enzyme. A ping-pong Bi Bi kinetic mechanism was observed. The Km for formate is 26 mM, and the Km for the electron-accepting dye, benzyl viologen, is in the range 1-5 mM.

Comparative genomics and mutagenesis analyses of choline metabolism in the marine Roseobacter clade [PDF]

, 2015
Choline is ubiquitous in marine eukaryotes and appears to be widely distributed in surface marine waters; however, its metabolism by marine bacteria is poorly understood.

Two‐Step Synthesis of a Chiral Fluorinated Alcohol With Silica‐Supported Enzyme RrADH in Batch and Continuous Flow Mode

Chemistry – A European Journal, EarlyView.
A two‐step process was transferred from batch to flow mode for the synthesis of (R)‐2‐fluoro‐1‐phenylethanol as a benchmark, consisting of a decarboxylative fluorination in aqueous media, followed by an enantioselective biocatalytic reduction of the prochiral intermediate with RrADH immobilized on silica supraparticles.

Molybdopterin cofactor from Methanobacterium formicicum formate dehydrogenase [PDF]

Journal of Bacteriology, 1986
The molybdopterin cofactor from the formate dehydrogenase of Methanobacterium formicicum was studied. The cofactor was released by guanidine denaturation of homogeneous enzyme, which also released greater than 80% of the molybdenum present in the enzyme.
