Groundwater Microbial Diversity Associated With Icelandic Basaltic Subsurface Environments

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Overview of microbial diversity and environmental drivers in Icelandic deep basaltic aquifers. Using 16S rRNA gene metabarcoding across 22 geothermal wells spanning broad temperature, pH, and bedrock‐age gradients, the study reveals distinct bacterial and archaeal community structures shaped by temperature, pH, and host‐rock reactivity.

Analysis of ligation and DNA binding by Escherichia coli DNA ligase (LigA). [PDF]

, 2005
NAD+-dependent DNA ligases are essential enzymes in bacteria, with the most widely studied of this class of enzymes being LigA from Escherichia coli. NAD+-dependent DNA ligases comprise several discrete structural domains, including a BRCT domain at the ...

Genetic transformation of the extreme thermophile Thermus thermophilus and of other Thermus spp

Journal of Bacteriology, 1986
Genetic transformation of auxotrophs of the extreme thermophile Thermus thermophilus HB27 to prototrophy was obtained at high frequencies of 10(-2) to 10(-1) when proliferating cell populations were exposed to chromosomal DNA from a nutritionally independent wild-type strain.

Substitution of CH3 by CH2F in 2‐Methylerythritol Cyclodiphosphate Triggers Potent Inhibition of IspG with Concomitant Fluoride Ion Expulsion

Chemistry – A European Journal, Volume 31, Issue 66, November 25, 2025.
The fluoromethyl analogue of MEcPP was identified as a very potent inhibitor of the oxygen‐sensitive [4Fe‐4S] metalloenzyme IspG. In the course of the IspG‐catalyzed transformation, this novel compound undergoes fluoride elimination, offering additional evidence for the involvement of a carbanionic intermediate in the mechanism of this enzyme ...

The actinobacterial transcription factor RbpA binds to the principal sigma subunit of RNA polymerase [PDF]

, 2013
RbpA is a small non-DNA-binding transcription factor that associates with RNA polymerase holoenzyme and stimulates transcription in actinobacteria, including Streptomyces coelicolor and Mycobacterium tuberculosis.

In Vivo Biosynthesis and Direct Incorporation of Noncanonical Amino Acids into Proteins

ChemBioChem, Volume 26, Issue 22, November 17, 2025.
This review evaluates engineered (semi)autonomous cell systems for the biosynthesis and incorporation of noncanonical amino acids (ncAAs) into proteins. While semi‐autonomous cells convert supplied precursors into ncAAs autonomous cells integrate biosynthetic pathways that produce these building blocks intracellularly.

Structural elucidation of phosphoglycolipids from strains of the bacterial thermophiles Thermus and Meiothermus

Journal of Lipid Research, 2006
The structures of two major phosphoglycolipids from the thermophilic bacteria Thermus oshimai NTU-063, Thermus thermophilus NTU-077, Meiothermus ruber NTU-124, and Meiothermus taiwanensis NTU-220 were determined using spectroscopic and chemical analyses ...
