Background: The phylum Thermotogae is composed of five families: Fervidobacteriaceae, Thermatogaceae, Kosmotogaceae, Petrotogaceae, and Mesoaciditogaceae; one class: Thermotogae; and four orders: Kosmotogales, Petrotogales, and Mesoaciditogales.
Method: There are thirteen genera in all. The physical and metabolic characteristics of the Thermotogae species reflect the extreme heat from which they were separated. Thermotogae members have a broad spectrum of metabolic capacities, resulting in a pool of valuable chemicals with potential uses in many different sectors.
Result: Based on NMR analysis, our findings demonstrate that T. maritima uses the EM route to metabolize 90% of glucose in anoxia and the ED pathway for 10%. On the other hand, T. maritima continues to employ the EM and ED glycolysis routes concurrently when exposed to extended oxidative stress; however, the ED pathway's contribution drops from 10% to around 5%.
Conclusion: Compared to the EM route, the ED pathway has more strongly repressed transcripts that encode its unique enzymes.

G-quadruplex structures in 16S rRNA regions correlate with thermal adaptation in prokaryotes.

G-quadruplex (G4) structure is a nucleic acid secondary structure formed by guanine-rich sequences, playing essential roles in various biological processes such as gene regulation and environmental stress adaptation. Although prokaryotes growing at high temperatures have higher GC contents, the pattern of G4 structure associated with GC content variation in thermal adaptation remains elusive. This study analyzed 681 bacterial genomes to explore the role of G4 structures in thermal adaptation.

Engineering non-native metal active sites into proteins using canonical amino acids offers many advantages but is hampered by significant challenges. The TIM barrel protein, imidazole glycerol phosphate synthase from the hyperthermophilic organism Thermotoga maritima (tHisF), is well-suited for the construction of artificial metalloenzymes by this approach. To this end, we have generated a tHisF variant (tHisF) with a Glu/His/His motif for metal ion coordination.
