ModE Regulates Alternative Nitrogenase Expression in the Methanogen Methanosarcina acetivorans

Molecular Microbiology, Volume 124, Issue 2, Page 105-114, August 2025.
During nitrogen fixation, the methanogen Methanosarcina acetivorans produces the alternative vanadium‐nitrogenase and iron‐nitrogenase only when molybdenum is unavailable to support the activity of molybdenum‐nitrogenase. Our work demonstrates that the expression of the alternative nitrogenases in M.

Transcription of the archaeal trkA homolog in Methanosarcina mazei S-6

Journal of Bacteriology, 1995
Transcription of the archaeal trkA gene homolog in Methanosarcina mazei S-6 was studied at the optimal growth temperature of 37 degrees C and after heat shock at 45 degrees C. Northern (RNA) blotting results (transcript size) and data from primer extension experiments to map the transcription initiation site indicate that trkA is cotranscribed with ...

Taxonomy and Halotolerance of Mesophilic Methanosarcina Strains, Assignment of Strains to Species, and Synonymy of Methanosarcina mazei and Methanosarcina frisia [PDF]

International Journal of Systematic Bacteriology, 1992
We examined 22 previously described and newly isolated Methanosarcina strains by performing denaturing gel electrophoresis of whole-cell proteins and assigned these strains to previously described species. Methanosarcina mazei S-6T (T = type strain) and Methanosarcina frisia C 16T were very similar in terms of the electrophoresis patterns of their ...

Qualitative Analysis of Microbial Dynamics during Anaerobic Digestion of Microalgal Biomass in a UASB Reactor

International Journal of Microbiology, 2017
Anaerobic digestion (AD) is a microbiologically coordinated process with dynamic relationships between bacterial players. Current understanding of dynamic changes in the bacterial composition during the AD process is incomplete.

Expanding the Scope of Orthogonal Translation with Pyrrolysyl-tRNA Synthetases Dedicated to Aromatic Amino Acids

Molecules, 2020
In protein engineering and synthetic biology, Methanosarcina mazei pyrrolysyl-tRNA synthetase (MmPylRS), with its cognate tRNAPyl, is one of the most popular tools for site-specific incorporation of non-canonical amino acids (ncAAs).

Spatiotemporal Control Over Protein Release from Artificial Cells via a Light‐Activatable Protease

Advanced Biology, Volume 9, Issue 5, May 2025.
Stimulus‐responsive protein release is essential for intercellular communication. Mimicking this functionality in artificial cells is promising to study the working principles of cellular signaling. Herein, an engineered light‐activatable protease is implemented in a coacervate‐based artificial cell platform to establish user‐defined spatiotemporal ...

Global transcriptional analysis of Methanosarcina mazei strain Gö1 under different nitrogen availabilities

Molecular Genetics and Genomics, 2006
Certain archaeal species can fix molecular nitrogen under nitrogen limiting conditions although little is known about this process at either the genetic or molecular level. To address this on a genome-wide scale, transcriptional analysis was performed on the model methanogen Methanosarcina mazei strain Gö1 using DNA-microarrays.

Linker and N-Terminal Domain Engineering of Pyrrolysyl-tRNA Synthetase for Substrate Range Shifting and Activity Enhancement

Frontiers in Bioengineering and Biotechnology, 2020
The Methanosarcina mazei pyrrolysyl-tRNA synthetase (PylRS)⋅tRNAPyl pair can be used to incorporate non-canonical amino acids (ncAAs) into proteins at installed amber stop codons.

Distribution of methanogenic potential in fractions of turf grass used as inoculum for the start-up of thermophilic anaerobic digestion [PDF]

, 2012
This study aims to investigate thermophilic methanogens in turf used as an inoculum. Results showed that Methanoculleus sp. regarded as hydrogenotrophic and Methanosarcina sp. regarded as acetoclastic methanogens were present in turf tested.
