BEAN and HABAS: Polyphyletic insertions in the DNA‐directed RNA polymerase

Protein Science, Volume 33, Issue 11, November 2024.
Abstract The β and β′ subunits of the RNA polymerase (RNAP) are large proteins with complex multi‐domain architectures that include several insertional domains. Here, we analyze the domain organizations of RNAP‐β and RNAP‐β′ using sequence, experimentally determined structures and AlphaFold structure predictions.

Biomarkers’ Responses to Reductive Dechlorination Rates and Oxygen Stress in Bioaugmentation Culture KB-1TM

Microorganisms, 2018
Using mRNA transcript levels for key functional enzymes as proxies for the organohalide respiration (OHR) rate, is a promising approach for monitoring bioremediation populations in situ at chlorinated solvent-contaminated field sites.

Reductive dechlorination of tetrachloroethene by a stepwise catalysis of different organohalide respiring bacteria and reductive dehalogenases [PDF]

, 2018
The enrichment culture SL2 dechlorinating tetrachloroethene (PCE) to ethene with strong trichloroethene (TCE) accumulation prior to cis-1,2-dichloroethene (cis-DCE) formation was analyzed for the presence of organohalide respiring bacteria and reductive ...

Functional genomics with a comprehensive library of transposon mutants for the sulfate-reducing bacterium Desulfovibrio alaskensis G20. [PDF]

, 2014
UnlabelledThe genomes of sulfate-reducing bacteria remain poorly characterized, largely due to a paucity of experimental data and genetic tools. To meet this challenge, we generated an archived library of 15,477 mapped transposon insertion mutants in the

Genome‐resolved metagenomics revealed novel microbial taxa with ancient metabolism from macroscopic microbial mat structures inhabiting anoxic deep reefs of a Maldivian Blue Hole

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
This study investigates macroscopic microbial mat structures found in complete anoxic conditions at 70 m depth in a Maldivian Blue Hole. Genome‐resolved metagenomic led to the description of several new taxa with ancient metabolism revealing novel bacterial genera belonging to the order Dehalococcoidales as dominant members of these communities ...

Coupled Adsorption and Biodegradation of Trichloroethylene on Biochar from Pine Wood Wastes: A Combined Approach for a Sustainable Bioremediation Strategy

Microorganisms, 2022
Towards chlorinated solvents, the effectiveness of the remediation strategy can be improved by combining a biological approach (e.g., anaerobic reductive dechlorination) with chemical/physical treatments (e.g., adsorption).

ARAGORN, a program to detect tRNA genes and tmRNA genes in nucleotide sequences [PDF]

, 2004
A computer program, ARAGORN, identifies tRNA and tmRNA genes. The program employs heuristic algorithms to predict tRNA secondary structure, based on homology with recognized tRNA consensus sequences and ability to form a base-paired cloverleaf.

Metabolic versatility of aerobic methane‐oxidizing bacteria under anoxia in aquatic ecosystems

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
Besides conventional aerobic oxidation pathway, MOB has four underlying metabolic strategies under anoxia: (i) forming a consortium with oxygenic microorganisms; (ii) self‐generation/storage of O2 by MOB; (iii) forming a consortium with non‐oxygenic heterotrophic bacteria that use other electron acceptors; (iv) and utilizing alternative electron ...
